What is this crap? How do I get rid of it?

[The Grizz]

I've got a couple patches of this crap that I have no idea what it is or how to get rid of it. Anyone got the solution?

Digitate Hydroid... It's the devil, I ended up throwing the whole rock out that the stuff was on. It spreads, stings and SUCKS!

Damn that sucks! I was wondering when I looked at it at your place, but I thought it was something you grew on purpose lol. Hope you find a cure!

Take a blowtorch to the rock

(Actually I'm not really kidding - if you do it though be careful, you don't want the rock shattering on you.)

Do you have any dwarf/pygmy angels (Centropyge) ? They sometimes will pick at it.

The problem with just scraping them off is that they burrow into the rock so you only give them a haircut.

You can sometimes smother them with epoxy (you can always remove the epoxy later) but this looks like a pretty large colony.

I'm thinking blowtorch or letting the rock dry out and reseeding it in a curing tub are probably the better silver bullets.

Good luck..

TORCH IT IS!! I think I have one of those somewhere around here. Luck thing is there is nothing else attached to the rock it is on. Thanks for the info Levi & Tony.

Good luck dude. Kill the buggers.

Aren't those colonial hydroids? Thought the digitate ones looked more like little white strings waving around.
If the torch doesn't work, a night in the deep freeze will.
