I would only put 1 dwarf gourami in. They fight all the time IME. The flames have been really aggressive for me. I've got a neon blue that is so peaceful he makes neons look like tigers.
yeah, but i gave the blue gourami away because a couple days ago i got a marigold platy and the gourami just woosh and kept on biting it, so i took my chances and just give it to my cousin
