So, I've narrowed down my fish choices to two. Tetra and Honey Gourami. In my ten gallon tank, how many Honey Gourami could I keep with, say, six Tetra? If I didn't have any Tetra, how many Honey Gourami could I keep then? Also, if I were to keep Tetra with the Gourami, would the Tetra nip at its fins? Thanks!
