Hello! I have 2 old rainbow sharks about 6 inches long that cannot be returned to the store. But the store salesperson recommended 2 dwarf Gourami would get along well in my tank because they are semi-aggressive as well. I used to have tiger barbs, but my last one just died. I have gotten bad advise at stores before (hence the 2 sharks). So I was curious if anyone else has this combo of fish & if they are compatiable? Are Gourami able to stick up for themselves in your experience? Thanks for the advice!
