Okay so i rescued a few fish from a friend the other day. I say rescued because they were in a small 2 gallon tank that was only three fourths of the way full and extremely dirty. I got two fish. One is some kind of eel, I think its a dragon goby but im not sure. its about 5 or six inches long. The other is some kind of catfish but its real dark and don't have any spots or stripes on it. Its about 3 to 4 inches long and had short whiskers. Il try to get a picture of it soon but i think it might be a wild catfish. It looks a lot like something i would catch in my local rivers. It also has a huge mouth like that of a channel catfish. Anyway the point if this post is what should i be feeding these guys? The catfish seems to eat tropical flakes but im not sure if it gets enough. Should i try to feed it garden worms or something? As far as the eel goes the only thing he will eat is dried baby shrimp and possibly blood worms. Any suggestions?
