I'm not sure if you guys can see it, but i'd like to know what the heck that is...looks like some kind of sponge. Anyone seen this before? Is it harmful or is it reef safe? Help Please

Looks to be either a sponge or a colonial tunicate.

 

[romeo0119]

it's white and not orange, isn't a colonial tunicate supoose to be a orage color?

 

[venwu225]

there are alot of different colonial tunicates with lots of different colors, same species may even have different colors...

 

[romeo0119]

if it was indeed a colonial of tunicates, is it bad for the tank? How to treat it?

Oh, no, tunicates are desirable. So are almost all sponges. Both eat phyto: they're filter-feeders, and improve the water quality. See if you can get a clearer picture: we're curious. Tunicates are hard to keep alive any time at all. What was the origin of the rock? What ocean?

imo, it looks like a sponge. tunicates aren't difficult to keep. my large tunicate have popped out a bunch of babies. the secret is to keep a skimmerless tank
