i woke up this morning and noticed this semi-transparent white cloud of stuff sitting at back of tank on my live rock. looks like soap suds sorta. are they eggs and if so, what put them there? do i just leave them alone and the fish will eat them? didnt notice any of the fish or cleaner crew even going near it to take a taste. just curious.

hrmm....thats a toughie without pics.

You do state it is at the back of the tank. If it is getting little or no current back there it may be a dying or dead small sponge.

If you cant post a pic give us a size in cm or inches and how far it raises up off the rock etc.

Offhand though without pics and such I would guess it is a dying sponge. If it wont disturb the tank too much then I would just remove the rock and scrub that bad boy off with a hard brush.

[edit] where was the live rock from? Florida live rock is covered in small sponges which usually die off.
