Hi fish peeps, I have a 17gallon cycled and recently added 3 Sparkling gourami. I see in other threads that having more is better. Plus I really think they are so cool to watch — the two males have displayed their fins and croaked at each other and are both pursuing the female (she might need a break!). In addition to the gouramis I’m thinking neon green tetras and otocinclus. Would I be able to add dwarf corys too? What would you suggest?
