The little swine - just of late, my gold gourami seems to have thought himself as a bit of a hardman and been treating the tank like his own !
I thought this was great originally, as he wasn't disturbing any others and all seemed well.
Upon feeding tonight though, for some weird & unkown reason, he has been almost bullying his counterpart, the pearl gourami (which by the way has just started to eat).
It literally chases him to the other side of the tank, usually forcing him in a corner up by the filter. Worrying seeing as they should be best mates really and he hasn't done it before.
