well in my 47 gallon i have 12 zebra danio's, 4 pepered cory's, and 3 i think pearl gourami's, idk what type but their blue and kinda chubby from being in a 5 gallon. i saw these net gold gourami's in the store like 2 weeks ago and was thinking of getting them. would it be okay for everything to add more gourami's or a different kind of fish. the gourami's seem to like it in their as they just kinda chill at the top and sometimes go to bottom. but i dont think they rlly like the active zebra's but still better than 5 gallon.
