Paired True Percula Clown Fight after Lights Off

bryanong · May 2, 2006

Hi All,

I bought a pair of true percula clowns from coral farms a couple of days ago, but the moment I off the lights the smaller of the 2 went bonkers and swam like crazy and the colors fades off. The bigger one kept chasing and biting the smaller one. I got no choice but to on the lights the whole night. But during the day when there's day lights, I off the lights and they dun fight. Is this normal for new fish? Can anyone please tell me how to prevent this? Thanks a lot.

actually i dun think this phenomena is normal as it never occur to mi in my entire reefing course . maybe the clown is paranoid . give it some time to cool down

Actually I encounter some similar problem. I have a common clown which is the biggest and 2 true percular of the same size in my tank. When lights off, the common will go crazy. He will just swim very fast and bang in to the glass. Damn weird.. :shock: For the two perculars, they will occasionally bite each other. Other times, they will just swim together happily..
