I just purchased some LiveRocks for my 300g tank. I put these LRs temporary in my 90g tank until the 300g is ready. I just turned on the light in my 90g tank and saw hundreds of these crawlers all over the glass. They move around like snails without shells. they disappeared in the day time when lights are on, and came out when lights are off.
Do you know what they are? Are they bad for saltwater? How do I get rid of them if they are bad for the tank?
Thanks.
