I have (4) Gouramis and I want to add a schooling fish to the tank. PetCo has a sale on Black Neon Tetras but I read on a site that they aren't compatible with Gouramis. If so why not? Can you think of any other schooling fish that are compatible with Gouramis, Corys & Otos?
I would like a nice schooling fish for the 36 gallon. I checked my fish compatibility site & they said no to Black Neon Tetras & Harlequin Rasboras
