I have this dottyback and before the upgrade to th new larger tank he was quiet and kept to himself. Now he has taken to bullying my yellow wrasse. the wrasse is still eating well as I make sure he gets plenty but he is always being harnassed and chased..luckily he is to fast fot the dotty. I now think th wrasse may be developing ich from the stress... how do i catch the dotty without pully the moth old tank down??? i remember recently reading about someone who always feeds in a fish trap....can you please step foward kind sir...as for the possible ich thoughts thx
