I've just finished draining my 175g bowfront into tubs, caught all the fish and filled the tank back up again. I've had an outbreak of marine velvet and I had to get all the fish into quarintine.
R.I.P 1 mandarin 4yrs, clown goby 2yrs, damsel 3yrs and a white cheek tang 6 mths
*Edit* Arrrg... Tigger, my favourite fish, just died. He was a potters angel
