I just caught a baby Largemouth Bass about three days ago and I have him/her in a 20 gallon tank with
2 Gouramis
4 Rosy Barbs
2 Bluegill
1 Panfish
4 Baby panfish
And I don't know if the Bass should have a tank to himself maybe with other baby bass or just leave him there with the others. My dad says that he will eat the baby panfish, but I think there to fast for it and it's very skinny because the creek he came from had no little minnows or other little fish that it could eat. :( So what do u think is best for him? :unsure: please don't say back in the creek cause all the fish that I caught over there are all so skinny and know he can have a nice place to stay, nothing that can eat him, and plenty of food.

Keeping native fish is really cool. Congrats on your catch! I think the lmb is going to eat all the fish in the tank. Even the ones bigger than he is. He's going to grow pretty quick too. I'd say keep him if you have the room, no doubt. I'd be moving the other fish, though, if you like them.

Be sure to post a few pics. I'd like to see a tank-kept lmb. :D

I think I would have done some research about putting a captured from the wild fish into a tropical tank. I think there are stages you should have gone through before just adding him to your tank.
His environment before is probably full of disease #1.
Changing the whole water temp, pH, everything of that sort, that list could go longer.
I did however catch some blue gill, but they had their own tank, and their own water from where I caught them from. They still didn't last very long, about 8 months. It is something to maybe read up on before actually doing it.
That is my opinion though.

I had a baby bass with bluegill, they were in their own tank and got along well with each other.

TammyD might have some advice on this one, being a Coldwater enthusiast.

I have to agree. the bass will eat everything in the tank. If the bass is small enough just give it some time. I had a peacock bass and at 2 inches it ate everything I put in the tank.

I kept bluegill for quite a long period. Bass too. Bass, as far as i know, will only eat live or sometimes frozen food. Sunnies swing over to flake easily. The bass will eat everything, and even though he's small, he will still beat on the other fish as soon as he gets used to his home. Bass make awesome pond fish, though.

He's still a baby and he's definetly not big enough to eat the bluegill, but he might try. The bass isnt' attacking anyone yet ,but the rosy barbs picked at for a little while then he started to hang out with the bluegill and they kept the rosybarbs away. I managed to keep my lake fish alive for about a year and a half,but I don't know whats a female and whats a male and I would like to try and breed them because I've managed to breed lots of fish without meaning to and I would like to try bredding them.

Bass will eat anything in that tank move the bass to another tank please

If the bluegill is the same size as the bass or larger, then the bass won't eat it for at least 1 year, because the bluegill will out-grow the bass for a while, but AS SOON AS the bass is big enough to fit the bluegill in it's mouth, it will eat it. The bass will definately eat the rest of your tank-mates, they don't stand a chance. None of them can out-run the bass by the way. Bass in the wild love to eat bluegill, in fact that's how I often catch bass (I fish for bluegill). If you're planning on keeping them long-term by the way, then you'll probably want a MUCH larger aquarium, as 5 of them will out-grow a 50g in about 3-4 months. If you have a spare 200g, that would be great for them.

They will do best in about 60 degree water, so you won't need a heater to do anything other than keep the temperature from swinging.
