I have a honey dwarf gourami and it gets along with everything in my 30gal no problem, platies, mollys, a female beta, a bumble bee catfish, and one lone neon tetra who had a buddy that got eaten by the catfish. The tetras are from my old step dads 5gall that I got handed and couldn't set up when he left and there were only 2 tetras with the beta. I do plan on buying 4 more tetras as soon as I can but money is a limiting factor when you have no cash flow.
