Coldwater fish ID!!!!

I was at my local lake with my sister chatting about random stuff and I found a small catfish of some sort. Of course, my ever generous sister braves the cold waters and catches him! The water is really, really, really cold. I'm thinking of keeping him in an unheated tank in a cold part of our house. But, I don't know what species he is or what he eats. Here's some photos:




Thanks!
P.S. I named him Leo because he looks like a lionfish! The lake he is from is called Kootany.

5 gallon
One betta
10 gallon
Two bettas, divided
Three mystery snails
20 gallon
Seven female bettas
Four oto cats
Five juvenile female guppies
One goldfish (temporary)
29 gallon
One dwarf gourami
Six tiger barbs

27 fish....

Definitely a goby or related species. You and the fish would probably be better off if you rereleased it, but if you want to keep it I would do some research on freshwater goby species and their needs and go from there.

I strongly advocate for re-releasing. Since you don't know the exact species, you don't know what it needs. Further, this isn't like a tank-bred fish - it's used to having the whole lake to swim around in. Confining to a tank seems unnecessary and restrictive. If it's omnivorous, it will be used to a varied diet of live food, which you won't necessarily be able to supply. You don't know how it will take to captivity, and I worry that you will be risking its wellbeing by attempting to make it do so.

You may have gathered, I am very against people taking catching animals in the wild.

Life.

I dont know about American laws but in NZ its illegal to release fish back into the wild even if its a native....but you could probably get away with it and no one will know
If you were to keep it you would probably need a chiller to keep the water at a stable cold temp. Wild fish can be trained to eat frozen or flake food, but yeah google everything about it and find out 100% what species it is

Keep the tank in your basement and if it's anything like most basements in a Canada, there's no way you'll need a chiller.

It's cute as heck but I would put it back for the ethical reasons others have mentioned.

you could research the lake you found it in.see what the lake is stocked with. some of the freshwater goby are endangered,this looks like one of the listed fish.it may have been a very bad mistake to take this fish. it is never a good idea to take native species without being able to identify them.in minnesota we have to have a license to have native species.i would return the fish a.s.a.p! i would think twice before doing this again.
