Hello!

I am new to the hobby and have come across a few critters on my LR that I can't identify...

Can somebidy please give me some input?

I can see movement inside this thing and it just recently started spewing something wierd out???

Then there is this fuzzy white glob?

Sorry for the camera phone pics...

Thanks in advance for any help!

#1 Vermitid Snail, harmless but reproduce rapidly and send out webs to catch food. The webs can irritate coral. Some reefers don't like them and simply shatter their tubes to kill them. I just leave mine be.
#2 Pineapple Sponge, harmless filter feeder
