Ouch...what's wrong with my poor anemone??

[stu]

Hey guys, i've been out of town for 5 days and when i got home i noticed something on my bubble tipped anemone....So i flipped him over and took a photo.....umm....it looks like he has some sort of a disease or something has been eating him? Any ideas? He seems to be relatively happy.. I've got 94W of HO lighting on him in my 100Litre tank. 2 x Actinic globes & 2 x normal globes.

Waters are as follows

Ammonia - 0
Nitrite - 0
Nitrate - 0/1
PH - 8.3 (stable)

I've got 1 Clownfish, 1 Yellowtail Damsel, 2 Brittle Stars, 3 Hermit crabs, 1 very very small white crab...and that's all that i really know about.

This is only on the foot of the anemone? Looks like the anemone suffered some trama or has gotten torn. Nothing really screams out at me in your list of inhabitants except for maybe the crab. How long have you had it? It is possible for the damage like this to heal as long as you keep your water parameters up and keep it happy.
