What the heck is this??

[Gordon Cashmore]

I have/had little soft looking scum on the bottom of my rocks. This is on the shaded side away from the lights. What are the white EGG looking things. Anyone know? I'm currently battling a Digitate Hydroid infestation, and I thought this might have something to do with them, but I can't identify it. I've posted the pic. Any ideas would be helpful. I've since thrown out the rock, but I had to get all my coral off of it.

Thanks for the reply. Exactly. Should have seen the rock. Did not notice all the old dead worms underneath. I just pitched it and boiled most of my rocks in my tank. Oops. They are all clean now.

How old is your tank? You're talking about battling things that are usually seen early in the tank's life and go away on their own.

I'd let things play out, you threw away a rock with life and awesome filter feeders on it that's good for your tank.

My tank is about 2 years old. I believe these things can in with snails I bought recently. They were encrusted with barnacles and fans. I thought they would be a cool addition if I could get the fans to propogate from the snails to rocks so I didn't dip. Ugh wish I was not so hasty. The rock had nice green polyps on it too. I got a lot of it tranferred.

When in doubt: observe. It's tough because you see something and you are afraid of it doing damage or being a pest and gut reaction is to yank it! I've done something similar before, I feel your pain.
