Herkemer - that umbrella - is that on coral or a LR? - looks nice.. are percula clowns compatible with that? Do anenomes cause lots of bio load on a system? As you can see I only have a 10 gal, but with only 2 damsels, not a lot going on in there. I'm thinking of an anenome or a feather duster. Any comments from anyone? Too much?
