Currently I have 1 honey gourami in my tank. I’m considering what fish to add next. Was thinking about one more honey gourami but I don’t want to overcrowd my 20 gallon. I’m strongly leaning towards either zebra danios or neon tetras with some Cory catfish in the future. So could 2 honey gouramis live comfortably in a 20 gallon with two other small schools of fish? Or am I better off keeping only the single honey?
