I have 1 dragon goby. 9 barbs 2 gold gourmis and 1 snakeskin gourmi 1 flying fox and 2 plecos also 1 catfish. The barbs nip at my dragon gobys rear fin. Although it seems to stay at the same lanth of damage (about 1 mm). I feed him at night. I don't think that my tank is what he was ment for. Plus adding salt to my tank doesn't help my live plants. Do you think I should give him away? If I give him back to the pet store, who knows what kind of fish tank he will end up in. I know I take care of him and make sure he gets food, but I don't like to see him hiding most of the time (not at night). What would you do?
