Fish Fanatic
Got a very nicely balanced 50gal with a number of zebra danios, dwarf gouramis and cardinals, the danios flit around the top of the tanks but everyone else is very calm. Then I bought a pair of cherry barbs as I've always liked barbs but didn't want the agression problems of Tigers, but the little guy has such an attitude problem, he turns psycho whenever a danio comes anywhere near him and chases it around the tanks until he finds another danio then chases that, but leaves all the other fish alone. This in itself is OK as the danios are fast enough to keep out of trouble but all the extra action has caused the cardinals and gouramis to hide in the plants so effectively that it now looks like i've got half my stock missing! Is his behaviour likely to settle or should I think about moving him?
