That's a beautiful tank and I love the clowns - do you have any other fish? There's a pink/purple flash in the pink pocc pic that looks like it might be a fishy. I was wondering what the 'ice cube' was doing there as well lol!
Whisptech, in the wild clownfish use anemonies as safe refuge from predators - anemonies sting any attackers but the clowns are immune so they are safe whilst they are in them.
