I've never had a Betta with other fishes in the same tank so I have no idea which I should avoid or which are a safe choice.
I just saw these glass catfish at the LFS and I fell in love with them. Are they okay to put in the same tank as a Betta? If they are, would a 10gal with 1 betta and 2 catfish be a good size?
If they aren't, what fish do you recommend? Keep in mind that I can only afford a 10gallon (I don't have the space for anything bigger) and how many of them could I put in there with 1 betta?
