I am just thinking of turning my hardwater 650 litre tank into a predominantly gourami tank (I already have 6 clown loaches, 1 clown plec, 6 bosemanns rainbows), possibly looking out for rarer types as well as the more popular. Are there any pieces of gourami common sense I might not have? Does this sound like a feasable idea (I'm not that interested in breeding)? I haven't been able to find a dedicated gourami society or website!
