What could these be on my live rocks...

hskim · #1 08/15/2005, 05:31 PM

I got some free live rocks from Reefer Rocks from Florida and I added it to my fish and base rocks only tank and there are some unknown live stuffs on the rocks. Iâ€™ve already asked it in the reef forum but no clear answers so I thought that photographers might know these things better.

This is a coral skeleton on the rock that came alive after couple of weeks in the tank. The skeleton looks like honey combs and the feathery exterior retracts into the skeleton when I touch it. What could this be?

This is some fluorescent orange spots on the rocks that appeared one day and these seem to be growing

Is this bubble algae and do I have to remove them right a way? There are about three different places that these are growing out of.

If you could help me identify these I would appreciate it.

Are they bad for the tank? Do they spread like wild fire? Do I have to remove them.

Give this article a read over( if you haven't already).
If it was my tank and I could reach this easily, I'd definately try to remove it. Anyway, all the answers to the questionsthat you may have about various bubble algae should be in that article I linked to.

i have some sponge that naturally grew outa the rock that looks like that when it first started out, but if you think it's bubble algea don't take any chances w/ it.

Don't look like valonia to me. Valonia looks like small green pearls.

That looks more like some kind of slime growth with trapped air bubbles to me.

I once pulled out a valonia a bit larger than a golf ball from my nano! Was going to take a photo, but I misplaced it :/

If you go to zenya's link there are all sorts of different bubble algae this could be one of them. And the green stuff is firm not slimy. It is growing in three different places and I think I'll have to take them out.

And the orange fluorescent spots were eaten by my flame angle so could it be some sort of coral? This stuff is growing in different places too and I'm worried about this also but my flame angle is eating them soon as they appear.

And nobody knows what the first picture could be, uh? I've seen this thing eat stuff that lands on it. I can't get good macro picture of it because it is behind the rock facing towards the back and I have to get picture of it from the side of the tank. I'll have to get 150mm macro lense to get good closeup picture of this thing or moved the rocks around.

Thanks for the advices.
