Looks to be some sort of sponge...was that portion of the rock typically shaded?

I redid the aquascaping 2 months ago. Haven't see this before today on the rock, there is another one w similar things. It's not in direct light and is slightly shaded

Here's a better pic of it that also shows something green that's been growing for about 6 months.

For sizing purposes that's the smallest size of formula one pellet by ocean nutrition.

Looks to me like you just have some healthy, mature rock

Can't say for sure that first pic is a sponge, but unless it gets invasive I wouldn't worry much about it. Green stuff definitely looks like a sponge to me.

 

[Miah2bzy]

Cool! It should be mature it's from scchase tank that he had in 05'

hmmm, well...that certainly explains it!

Thanks!!! I've been trying to figure out the green stuff for some time now and should have just posted here months ago. Thanks again!

Now that I'm home and can see this on the PC...first pic looks more like a tunicate than a sponge.

http://emeralddiving.com/id_ascidians.html - not necessarily the same sp. but looks similar to the one in the 2nd pic on this page

Anybody else wanna chime in? I'm no expert...just going off my own research after having random microfauna like that popping up in my tanks.

 

[Miah2bzy]

Yea it looks about the right size to. I get them blowing around the tank a lot and it collects on the dragons breath macro

Looks like this is solved! Nice. Never really had a tunicate before
