I have these lil brown like things on my rock. I don't think they are snails (no shell) I can see them moving. They are on the sand and rock. they are very small and kind of flat squares

Flatworms. Do a search and weep.

Sorry.

Sounds like flatworms. Do a search on "flatworms" and you will find many threads on them.

Here are some links:

Bet you could post em on eBay as nudibranch food and get $50 a dozen, they'll buy anything.

I feel very hesitant about introducing any kind of chemical in my tank (excluding pH alk and cal buffers) no matter how reef safe they claim they are. I have room for a predator I always wanted a six line ( lawn mower and goby reside at this time). I am moving to another Apt. the beginning of the year so I cant introduce and will just have to deal w/ the worms for a while. Any word on what these guys can do to the leather inhabitants in my tank.
