Tiger Barb behavior normal or not?
I have a 55 gal. tank and several fish (all mildly aggressive) from tiger barbs to gouramies..all of which are fun to watch...however I have noticed that the tiger barbs are acting unusually different. They are now swimming with their noses pointed downward and staying together almost hovering in no paticular area but they stay together. Their bodies look quite normal just that their color changes as if they are getting darker, they almost look as if they are vibrating or shivering. I have had them for several months now and just started this behavior.
