My 40 gall tank has 3 Rosabra (sp?) Hets, 3 neons, 2 swordtails, 1 CAE, 1 kulji (sp?) 1 pleco, and 2 upside down catfish. Do you think it would be ok to let Ari, one of my male bettas, become part of the community? The only reasons he isn't right now are I had a paradise fish (which just died) and I'm not sure if these types of fish would be a good mix. I know it can all depend on the fish, but I wanted your opinion. Thanks.
