Eunicid worm?

 

[celacanthr]

Eunicid worm probably, because of the size.
It may be dangerous, or it may be safe. At that size it would probably dangerous to smaller tankmates. They make interesting pets, in a suitable tank.

in the process of changing aquariums, my inlaws discovered this. Theyve had their tank for approx 2 years but havent been able to maintain corals - is it possible that this was eating them? Or should they not be fooled by this and keep searching for a crab - or would it be their water parameters? With the exception of one to 2 fish, the rest are all doing very well.

 

[celacanthr]

This very likely may have been the cause, since some (not all) eunicid's eat coral.

And it looks like that little crab is his next victim.

does that resemble a teddy bear crab to you guys? I asked that it be saved and put into our tank, but it was already to late - they disposed of them both
