i have a proven breeding pair of wild true percula clownfish! i have had them for about 3wks now and they are in my reef tank with 30kg mix of live and new ocean rock and few turbo snails. they are always doing the clown wiggle and cleaning the terrcotta roof tile i put in for them to lay eggs on she looks as if she is fat around the belly and they both have what looks like a strand of white hair coming form there bellys i think these are there tubes for eggs and sperm! but i have not had any eggs at all! they are 4yrs old (i was told) so what is wrong why no eggs?
