Could have been a rock crab...haven't seen the crab for awhile, think its been hiding in the rock work...was told it was an Emerald at the store...but they may not have known... Don't think the clowns would have torn the starfish leg off....Haven't seen a mantis...but it could be. Just surprised I haven't been able to find the other clown.

The yellow tang and coral beauty seem content, and actually have been more active since yesterday which makes me wonder...but doubt they had anything to do with it....

Just trying to make sure I dont get an ammonia spike from the other clown so will probably go look for some Ammonia control chems to make sure I dont cause the tank to cycle again....The tank is a little over 6 months old so not sure it could handle a spike...

The rock work didn't looked disturbed from when I left in the morning....but don't rule it out either....just wish I could find something of the other clown....very strange......

Thanks for the info though....
