I have a pair of clown fish for sale. The smaller one is black & white misbar and is about 2.5". The bigger one is regular ocellaris which is about 3".
Yes, but not proven. I got them from a tank deal and the guy had them in his 50g for a year already.
They are doing great in the quarantine tank after the move. Both are bitters as they were getting pretty aggressive toward my hand as I was taking out live rocks.
Never been bitten by fish before...but well, there are always first times.
