I've looked at many websites on A. Clarkii, but can't find any sites on their behavior. If anybody knows of any good clarkii sites let me know. How long until he (she) will become acclimated enough to stay out in the open? Or do they tend to hide. He comes out into the open when I'm not around as i can see him happily swimming around from a distance, but as soon as I get close he scurries away and hides in the rock. It's hard to monitor his eating habits or health when he's always hiding. He is the only fish in the tank. I had Ocellaris Clowns before the Clarkii and they weren't shy at all. I'd appreciate any info on Clarkii Clownfish. Thanks!
