Is this Ich?

I noticed this cloudy white stuff underneath an overhang on one of my rocks. I've seen freshwater ich before and it looked kind of like this. Can anyone confirm if this is ich? If so, what should I do?

Ich is a fish disease......you wouldnt see it on a rock.

I found this and it made me think that it may be trophozoite phase of ich.

"After several days of feasting, the engorged parasite develops into a trophozoite, burrows out of the fish and sinks bottom of the tank. Secreting a soft jellylike substance, it forms a protective membrane inside of which it divides into hundreds of baby parasites, known as tomites. The hungry tomites soon leave their home in search of a fresh fish to dine upon."

Hey Zen, no worries..... the ick parasite (in any stage) can't be seen by the naked eye. It takes a low power microscope to check out these little rascals. I can't see exactly what you are showing us, but it is most likley sponge of some sort. Most prefer dark spots to grow, and won't ever emerge into the light. If you want to, get a good close up and bring it to me. I'll look it over and try to identify. Or, if you don't want it in the tank, scrape it off and I'll take a look at it.

Thanks for the info guys. If it's not dangerous, I'm fine with leaving it and seeing what it does.
