A couple id's
 

i have had these in my tank for quite some time. they dont seem to be bothering anyone, moving or getting larger. finally got off my butt to take some pics and find out what they are.

first up is a little white ball (size of quarter)- looks like a little soccer ball with tentacles coming out of it- picture is dark so it looks green, but i assure you its white

second is this little fuzzy thing growing on the rock, looks like it has a few centers and its the size of a dime- looks like the start of a furry mushroom, but it isnt one.

what do you figure canreefers??

The first one is a sponge. The second one I can't tell from the pics and don't even have a guess :mrgreen:

Definitely a sponge in the first pic. And like Marie, can't even hazard a guess on the second one! No idea.
