I got a nice piece of Xmas tree rock from Seasave a couple of weeks ago, with 8 worms.
A couple of days ago I noticed one was missing...so started to worry.
Then yesterday I was down to 6, worrying more....
Tonight I come home and find a hermit crab (1/2" shell) perched on top of the rock. He hopped off as soon as I got close to the tank, and I swear I could see a guilty look on his face
I'm pretty certain the hermit wasn't picking at the Porites itself, coz it's as healthy as can be, with great polyp extension (for a Porites).
Do y'all think I've found the culprit?
Or maybe the worms just aren't getting enough food (although they look very healthy, haven't shrunk, etc.), dying, and the hermit's just snacking on their remains?
Thx for any advice,
