I bought a pair off OCC Clowns about a while back, while I had the pair in the tank I could put my hand in there when ever I wanted to. however the female decided to try the nemo excape route, DIDNT WORK. so I replaced her with the closest size male clownfish i could hoping that eventualy one of them will follow natures path or what ever the scientific name for it is. Well the old male naturaly started to turn into the female.I think he/she may be the biggest A$* I have ever seen I cant put my hand in the tank without having a flicking war with the fish befor i get done what I have to. this clownfish bites pretty good for her size, the pain can draw blood
