I recently added a second male dwarf gourami to my 20 gallon. The other occupants are a school of corys. Within a day the original male dwarf in the tank couldn't eat or leave the corner of the tank, as the new dwarf, who is considerably smaller, is a real bully. As a result, I have separated them by putting the new dwarf into a new tank. The original guy hasn't recovered yet though. What should I do? Is there a possibility they could get along or should I just drop the idea? Any help would be much appreciated.
