My Golden Tiger Barb keeps rubbing on my fake anemonie (did I spell that right?) and rubbing on the decorations and stuff. Is anything wrong with him? He looks perfectly normal.
what are your water parameters? Does the fish do this continuously or just every now and then? Most fish do this at some point in time but they do not do it constantly unless something is wrong. HTH
barbs often do that i think
i keep rosy barbs and there in the best of health but they do seem to choose a rock(usually smooth) and rub against that quite often.
But i think it's good policy not to have anything to sharp or jagged in the tank no matter what fish you keep!
