I have a pair of clownfish. They follow everywhere the other one goes. Just recently they been nipping at rock surface, glass walls , pretty much any surface in the tank. They would like kiss.. shake and alot of twitching and then go side by side and rub their bodies together. It sounds like they are in love? hahaha.. tell me wassup guys... If they are.. i wanna be totally prepare. By the way what do new born clownfish eat after they taken up their sac?
