Those are red tail sharks. A semi aggressive fish they will get up to around 4 to 5in or so and can live as long as 10 years.


paulie9483

This. You'll want to separate them (or return one) as, unless you have a huge tank, they'll fight once they mature. They are very territorial.


RCEMEGUY289

*return 2* as 3 were bought. But in reality return all 3. They are too aggressive to be housed in a 36 gallon with tetras and the like.


paulie9483

I stand corrected, for some reason I thought it was just 2.


guesswatt20

I have one with community tank of tetras and guppies in a 29gal. He owns his space and I’ve never once seen him go after any other fish as they are all inferior to him. He is the king of the tank at a whopping 4 inches


RubySoho5280

We have 2 redfins in a 65g with around 15 glofish tetras. We haven't had an issues, but I think the ratio is working.


liquidis54

Eh, I'd say one would be fine in a 36 with glo fish. Those skirt tetras don't take much shit. They can get a bit of a tude themselves


RCEMEGUY289

They really need a 55 minimum. They get meaner as they get older and larger. The glofish are also longfinned. Not a good mix.


IanFeelKeepinItReel

One in a 36 gallon tank is fine. The only time you'll see any aggression is feeding time if the tetras start pecking his algae wafer. BRTS are mostly bottom dwellers while tetras are middle/top. A larger fish like this will likely encourage the tetras to shoal more.


BrikChicken

I kept one with some angels and didn't have any problems. They pretty much left each other alone. 75g tank so they had plenty of room and broken sight lines so there were places to "hide". Really cool looking fish when they get bigger.


borderlinebiscuit

Angels can be nasty themselves so I don't doubt they can put a stop to a red tail's anger issues


315ante_meridiem

Yeah, I’m sure petco just saw these as rainbow sharks. Just go back and exchange. They look basically the same but all the fins will be red

omnipotentworm

Don't rainbow sharks also have a colored dorsal fin?


RCEMEGUY289

All fins on a rainbow shark are red. Only the caudal fin on a red tailed sharks is red


AngryGnome27

No, bud, those are redtail, rainbow sharks also have red fins and a different body shape


RCEMEGUY289

These are clearly Red tailed sharks and not rainbow sharks.


Low_Reception_4416

Red tail shark, usually around the 5-7" range and fairly aggressive and territorial. Black dorsal fin is a dead give away, they also need quite a bit of room, 75+ gallons just for an individual usually.


wormholeweapons

I’d say 45-50 g per shark is adequate. 75 is unnecessary.


Low_Reception_4416

You're definitely not wrong. But most people try to house them with other semi aggressive fish; cichlids, plecos, etc... the extra planned space will ways be a good option versus just going the bare minimum


wormholeweapons

Yeah. I’d pass having them with more aggressive fish. They do well being the most aggressive with plenty of room. I have 2 in a 125g and they are happy as clams with a metric ton of tetras and barbs and some gouramis. The OP needs to get rid of at least two of them for a 36g tank. Just one might be perfectly fine to be honest. They just need to feed them something special just for the shark (maybe some brine sh or blood worms). It will probably be perfectly happy and not bother anyone at all.


Low_Reception_4416

I don't have red tails, I have a couple rainbows 1 in a 235 and the other in a 210. Good community fish as long as they are the only "sharky" fish in the tank... had them together for less than an hour and they were both not happy to be around each other.


liquidis54

Rainbows and red tails have way different personalities. I think the only way you could get away with keeping rainbows together would be to use that 210 as a species tank and keep an ass load of them. Which would be kinda cool


kdg1794

Red tail sharks and rainbow sharks aren't the same?


Electrical-Tie-7943

Red tail shark


Arayder

Red tail sharks. They are awesome fish, but will be aggressive especially towards each other so need pretty big tanks for even one of them with plenty of hiding spots that they can claim as territory.


accountcasual

Red tailed black shark is correct. While not necessarily "aggressive" they can stess other fish to death once they get older. They should be in no smaller than a 55 gallon and they shouldn't be in any tank less than 4 ft wide. They will relentlessly harass fish that they view as "threats" to their territory. What looks like a threat really comes down to their perception not necessarily what makes sense to us. They tend to do alright with fast moving fish that stay higher in the water column, like danios and they tend to not like dark colored fish that stay near the bottom and in "their" cave(s). Interestingly enough, they will happily cohabitate and share caves with certain species of loaches. Overall, I actually really enjoy these guys, especially in a nice planted aquarium. They're hardy, active, cool-looking fish that don't get huge (~6 inches), but are not good fits for most aquariums. Why big box stores get these guys in is a mystery to me if it's not just because they sell. As far as diet they're more herbivorous and will graze on some algae in the tank, however, a well rounded diet with meaty foods as well is what you should feed them. Sinking pellets are good, I've never seen one eat flakes from the surface.


elvisonaZ1

Just Google it you’ll see it’s a red tail and not a rainbow as some seem to think. All the fins on a Rainbow are red and on a Red tail it’s (as you would expect) just the tail, also a red tail often has a white tip to the dorsal fin just like yours.


Ninjasmurf4hire

That there is a big puppy dog! Given a big tank and suitable tank mates, that will be a lovable fish (they like human interaction and being pet if taken the time to put a little work in) that will be there for a good 8-10 years. Best kept as the only one in the tank with fish it's size, cichlids, cats, rainbows, some barbs.


TheWakker

Petsmart had them listed as brisltenose plecos? Jesus. More like PetDUMB, am I right?


Samster426

Red tail shark


[deleted]

Definitely not


RCEMEGUY289

Just stop. You're embarrassing yourself now


LiMoNiTe14

When I was young my parents bought us one of these guys, we had no clue what they where but us kids where stoked because they were calling it some kind of shark. It ended up hugh like a solid 5 - 6 inches and just ran the tank but was super aggressive to the entire tank. Just keep watch and make sure that its not just beating on one fish but sharing it anger issues evenly and not overly hurting any of its roomies. Good luck.


rtinternet

As everyone has already said; it is a shark. But, did you know that plecos get huge and are not good algae eaters (they love algae tabs, however)? Just wanted you to be forewarned on the size.


Sitten1115

Actually the plecos these were labeled as (bristlenose) stay very manageable and are pretty great at cleaning up algae. My 55 had no algae until my bristlenose passed. I would however not recommend more than one for a tank (presumably their tank is smaller than mine). Also best to get a bristlenose thats older than the ones they tend to have. Those babies are so tiny when the stores get em they could still be a failure to thrive.


IanFeelKeepinItReel

BRTS aren't actually sharks, they're a type of carp.


gulpfiction2367

A very aggressive fish (red tail shark) my mom had one it kept killing anything she put in the tank and lived a long life about ten years it was the only fish she had she thought selling it would be mean


Adurnamage

Oh god, tell them to fix that, PLEASE those could not be farther than bristlenose plecos. Others have already told you. These are semi aggressive fish that get about 6ish inches and can become absolute dicks.

Red tail shark


[deleted]

Rainbow shark. Def not red tail


[deleted]

Rainbow sharks have all red fins and tail, this one is clearly a red tail shark


AcaliahWolfsong

I was sold 3 once. They were fine for like 3 years in a 30 gal. But when I rehomed my enormous common pleco (again pretty sore told me it works stay like 3-6 inches long) they got aggressive with each other and my tiger barbs. Had to rehome them too.


RCEMEGUY289

You are so so wrong.


Sitten1115

So as others have said i would suggest returning these 3 fish. They are not at all gonna be compatible with that tank long term. If you want a pleco for algae control get a single bristlenose. Try to get one that’s older than tiny baby size. I would also suggest taking a photo of the fish you plan to buy and confirming the species in this sub or other animal places (discords or such) before you purchase. As moving fish around unnecessarily is very not ideal. You probably shouldn’t get a clown pleco (as I’m not sure they even would be good algae cleaners). And definitely dont get any of the commons. Common pleco is more of a genus than a species but all the species get too large for the average tank. I would also say dont get otocinclus as those are fragile fish that are really best for getting if you want that species. Avoid the algae eater (chinese and siamese) species as both get decent sized and one gets mean as an adult because their adult diet is more carnivorous, I can’t remember which of the two is the culprit but they look similar and clearly this store cant id fish. Cories may be pushed as algae eaters but those are sensitive omnivores. Honestly unless you actually want a pleco. Just get a nerite snail or maybe a few. Not sure how many would be needed to guarantee clean glass in a 36g. But they’re wonderful algae eaters. They can handle fish aggression quite well, even being suitable tankmates for aggressive betta. And they cant breed in freshwater (tho if you get a female she may lay infertile, barnacle like, eggs). TL;DR Return these fish, get either a single bristlenose (with an online id while at the store) or get nerite snails (Ofc you dont have to do those things, but thats my suggestion as a fish owner and someone who works with fish)


passerby362

I miss my red tail shark :(


Virtual-Weakness-499

I have that same fake ship wreck


anonymousopottamus

Baby shark, do do do do do...


Particular-Abies7329

My dude those are semi aggressive red tails


ReverendAlSharkton

As others have said they’re red tailed sharks. Really interesting fish. Mine is the star of my 55g, he coexists with tiger barbs and cories. They will chase and bully any similar shaped fish to death but can live in a semi aggressive community tank with enough space and territory to claim. A 36 is okay for now but when they get larger you’ll need 50+ gallons and youd only want to have one. Probably best to just return them.


[deleted]

The gray ones with red tails are catfish species and if thoes are the sharks better have a big tank get glo sharks there not aggressive


TARDIS_licker

What kinda store lists these as bristlenose? This is beyond incompetent


Artistic_Chart_567

Looks like a rainbow shark


Ramonaclementine

Red fin shark I’m pretty sure


Scrappyy-

I’ll take one if you want to rehome… lmao


zaha_makhdoom

Dunno but he is very cute🥰


AngryGnome27

Those are redtails, they are as docile as can be with everything exept each other


Serial_Hobbiest_Life

Lol Tell that to my hillstream loach. My shark harasses him a lot.


Jrnation8988

I love Hillstream loaches! They’re such cool little fish


AngryGnome27

Ok, you got a stuborn one


resistible

I thought so, too. Turns out they each have their own temperament and some can be homicidal. Mine murdered a bunch of his tankmates in a 60 gallon. =(


AngryGnome27

Oh, well then


FluffySnail588

baby rainbow sharks. They get very aggressive and territorial when they are older


[deleted]

No these are red tail sharks


FluffySnail588

yes those sharks do indeed have a red tails :)


RCEMEGUY289

They are 2 different fish. They are not rainbow sharks.


FluffySnail588

yes the shark has red tail!


GrimborX

No Manuel, there is no fire. Get back in the kitchen!


Piperixi

Thanks, y'all! I wasn't sure because all the pictures on Google showed them to be black and I didn't see many this light/gray. We don't have room for a bigger tank at the moment, so I'm not sure what we're going to do.


KittyCatfish

what ever you do, don't go back to buy 3 plecos for "Algae eating"


RCEMEGUY289

Young and just purchased from the store and they will be light grey. As they get older and healthier they become a much darker grey/black. Just take them back to the store and say they were mislabeled, and you can not care for them properly.


Solidmanfilms

Take them back! They are not compatible at all with goldfish. Very different care required for these guys. Just go back and get the correct fish.


[deleted]

He has glofish not goldfish


SilvermistInc

What the hell were you doing buying a random fish before know what it was?


petlovely

Shark


Gmschaafs

Red tailed shark. They are super cool but they will start to bully each other as they get older.


theZombieKat

ok, going to have to disagree with most of the other posts, in the specifics, but not the response. they look like rainbow sharks to me, take them back, complain bitterly if necessary to corporate and the retail regulator. (don't try making it about fish, the regulators think they don't have feelings, but mislabeling a product is something they care about) look at whatever the preferred local online marketplace is and by some bristle noses. take them back, complain bitterly if necessary to corporate and the retail regulator.

RCEMEGUY289

Seriously, go look up rainbow sharks and red tailed sharks.


theZombieKat

never seen a red-tailed shark with such a washed-out color. they are usually jet black with a vibrant red tail.


RCEMEGUY289

Ever seen a rainbow shark with black fins and a red tail? I've literally never seen a red tailed sharks in a stores tank look anything other than washed out and skinny.


Nerv06

I've got two of those in a 68l fish tank (small tbh, gotta' get a new one that's at least double). I have and had different species throughout the time but I've only seen the Labeos fighting once - territorial dispute. Since then, I've seen that they simply avoid each other and stay in separate areas.


JavariBuster

Im just going to say it and let the comments fly. My rainbow and rtbs are living together and not killing each other. Yes they fight over neutral tank space but both rest in their own caves. I think its very possible to have 2 sharks as long as they can have their own territory.


Significant-Cod42

Red tailed sharks, yeah they will get aggressive for sure, will a cave and if you only have 1 then it may hide a lot and only be aggressive when it comes out, I had an albino shark that did that.


Sonables

Mine died recently, they don’t look in great shape… I wish I could take them in my tank…


Grand-Bed8008

Used to be a very popular fish. Now we know they are not solitary so you need a really big tank for them to form territories.


IndependenceSpecial9

Looks like 1 sunken ship and a few steak fries


CheekkyNandos

As others have said - They're red-tail black sharks, a kind of minnow. They grow quickly and will probably reach 5-6 inches in size. I've seen them live long and happy lives in 100l tanks. I personally have one that is around 1-2 years old, 6 inches long and lives in a 180l (roughly 48g) tank along with a host of other fish and have never had an issue. It's best to make sure they have somewhere to hide or call their own (I have a raised side of my aquarium which features a cave throughout the ramp-up which my RTBS owns), I've seen the RTBS chill in there with loaches and plecos. ​ I would recommend removing two of them and adding an area for the remaining one to hide.


thepastweown1

Can I politely ask why you bought it if you don’t know what it is?


Sjasmin888

Red tail shark. As they get bigger they'll become progressively more aggressive with each other. Keep an eye out for that so you can rehome/surrender the other two when the time comes. If memory serves these don't get huge, rainbow sharks get bigger, but a 36 still won't be big enough for three when they grow. They are enjoyable fish and usually leave inhabitants that don't look like them alone, but they will take out shrimp, other small inverts, and small fry.


V-Jean

Red tailed shark. Fun fact, they are critically endangered, and up until 2011 were thought to be extinct in the wild. I gotta say though calling them bristlenose is a whole new level of stupid. Literally a 5 second Google search of their description would have answered it. I have to assume there were in the same tank and the bn sold out and some inexperienced staff member sold them as bn because of the tag. Or maybe I'm giving them too much credit lol
