We just got a pair of occellaris clowns - 1st fish in our 55 gallon tank. They have sort of "dug" an area of the sand out in the back corner of the tank. Every morning we find them there sleeping, if that's what clownfish do. I was wondering if this was normal behavior?? Also, we have pellets for them to eat.. They are sinking pellets though and aren't too crazy about them. They'll catch them as they fall but then spit them back out. Sometimes will try to eat them off the sand but usually gets sand in their mouths and decide not to eat. Any suggestions?? Otherwise they are doing great, swimming around all over!!
