My friends clownfish already changed sex and you can easy tell which is the female and which is the male. When should they start laying eggs? She wants me to help her raise them and take care of them. Also are they ocellaris or percula? Its always hard for me to tell the difference. Here is a pic of them in their 55 gal tank, there is a rock where they are now but the urchin is still there should i move it?
