    Nothing to worry about, simple filter feeders.

    I would guess #1 is a tunicate, #2 is a sponge.

    That's cool something growing that's not bad hehe. I have one other thing growing that I don't know what it is. It's about 3/4 of an inch and they are growing in most darker part of the tanks. Thanks for the help. saitoking
