i really wanted to name my post HELP because i am very confused. i inherited a 5 gal fishtank that had originally 6 fish, which i dont know but maybe someone can help me zero in on their species.apparently 1 is supposed to be some sort of "shark" my sister was into that kind of stuff

the second night i was taking care of these fish, the tank leaked half its water. so i went to the store and bought a new similair 5 gal "topfin" petsmart tank with the in tank filter and light fixture. ive been feeding some tropical flakes and some pellets, i dont know which are for which fish lol. so anyway i had to put them in a little bucket while the water temp in the new tank normalized but hurridly put them back in as 1 of the little red black fish died in the bucket.

current situation:
so far ive lost 2 of the black/redtipped fish and have 1 left
there are 3 of the bigger 1"-3" long ones with whiskers
my PH meter reads, 7-7.4 and my ammonia is between caution-stress-danger up to .05 T_T
and i replaced 30% of the water in hopes to lower the ammonia

Please help me identify my new fish

hello and welcome.
hopefully someone will be along soon to be a real help to you.
the only fish i can ID is the Red tailed black shark,they like lots of places to hide,and
i think are agressive,i am unable to help with the other two.
it looks like you will be in need of a much larger tank,if you would like to keep these fish.
did you add dechlorinater to the new water ?

Its actually a red fin shark or rainbow shark - not a red tail (which only has a red tail rest of the fins are black). It will grow up to 6 inches and needs a tank of at least a minimum of 55 gallons. I can't be sure what the others are - they look like columbian sharks (really catfish) maybe - I would assume that they are also going to grow very big.

A 55 gallon tank seems daunting, but really its considered a beginner's tank because its easier to take care of, as far as water quality issues, illnesses, etc.

Believe it or not, but a smaller tank is A LOT more work. I didn't realize this until I started with a 14 gallon tank. It was a lot of work - water changes constantly - Nitrite spikes - Ammonia spikes - I was testing it and changing water ALL the time.

Check craigslist for bigger tanks I got my 55gallon for $100.

Good luck and don't give up!

if anyone has kept tabs after yesterdays post on this thread, i think it might be a gunthers catfish, horabagrus brachysoma. whew, i think i was worried that if it was a columbian shark catfish i would have to end up slowly changing to saltwater., which i dont think their tank mate would very much enjoy:shock: BUT i am still not very sure if the brachysoma is cool in freshwater, totally....
gunther = AKA: sun/eclipse/bullseye catfish

LOL - I don't know much about the other fish I'll admit - I just googles some pictures!

I only know about the red fin shark because I had one and he was the most playful little guy, but he started to get aggressive in my community tank and I had to rehome him.... I do miss him a lot.

The fish in the top pic look like a type of catfish.

I think you mean 0.5 ammonia? Because 0.05 wouldn't be in the danger level... though it's still bad, it's not something to panic about... Do some more water changes though.

Welcome to TFK!

The cats are Horabagrus brachysoma. These guys will get to be 18" so need a 75g tank minimum (though something 24" front to back would be ideal, the smallest of which would be a 120g). Really not fish that can be kept in a 5g tank as they will get larger than the tank itself. When full grown, these cats might be able to eat the rainbow shark. They're also quite nocturnal so don't expect to see much of them during the day.

If you're intent on keeping these fish, you really need to upgrade to a tank that can house them long-term as soon as possible. If you just want a smaller tank that's less of a commitment, I would return all three fish as none of them can be kept in that tank long term (the rainbow shark will reach 6") and instead get some fish that can be kept in a 5g for their whole lives.

Where do you live? The catfish are a tropical species so unless you live in the tropics they'd likely die if put into an unheated outdoor pond. I think finding them a good home via craigslist or taking them in to a good LFS would be a better option.

I live in arizona, its pretty chilly right now but i would check if it was heated first. that brings up a good question ive been meaning to ask. you can just ask them to take them from you?

I would not put them in a pond. Most LFS will take fish. Some only as donations (will not give you store credit for them), but some they will give credit or trade. Either way, you can take them to a good LFS and they will rehome them for you.
