Is this brown yellow algae good or bad?

Is this brown-yellow algae good or bad? If bad, how can I get rid of it?

It's on a third of my live rock, and it has grown thicker on that live rock since I got the tank (about a month or so ago), but has not spread to most of the live rock. It seems to prefer a certain type of live rock with lots of pores.

Previous owner said it was always present and not to worry about it.

I have a 120 gal aquarium with only two small fish (waiting to add more in two months after my new QT gets through cycling), but a fair amount of soft and hard corals. I probably don't have enough snails (maybe 2 dozen turbo snails, two hermit crabs, and a few other larger snail types).

Hard to tell, could be dinos

You need to get rid of it if it is growing on those coral skeletons. It will go to live corals next.

I found this thread on controlling dinos: http://www.reefcentral.com/forums/showthread.php?t=2307000

I'm having a local tank expert coming by today to confirm whether or not they are dinos.

Dinos are sorta square individuals. They get together in a mass usually. The pics don't look like dinos from what I can tell

Looks like stinging hydroids to me. THey're a pest. You can treat the rock with a hydrogen peroxide dip---30 seconds in h202 as comes from the drugstore, wash, rinse, Prime, repeat, then replace in tank.

This is embarrassing if true, my LFS expert (he's been doing it 12 years) dropped by and said they are coral...the live part of the coral. It makes sense, since where I'm seeing it is only on the "rock" with pores. Wow, am I a newbie!
