Black Sponge

My tank is growing black sponge. Wondering how common it is.

It can bee seen at the bottom of this rock and between the mushrooms on the top.

OMG i love your mushroom rock. Never heard of black sponge though.

Are you able to get a better pic of that? Interesting.

I've got some black sponge (along with a whole bunch of other sponges I've never been able to ID). Mine kind of grows like a mat over the rocks. How about you?

i posted something somewhere sometime ago on a rock with black sponge and people told me not to worry
actually i think seahorsefanatic was the one that said hes seen it a few times and its not harmful.

I've had some of the same black sponge before. Coincidentally it was also on a purple mushroom rock.

black sponge was the only thing I ever noticed my Blue Linckia eating.

They are quite common. I have black, yellow, orenga, white and pink sponges growing on my liverock.

They usualy start to grow after the aquarium as matured a bit and if there are enough nutriment in the water. Zeovit Sponge Power will help them grow.

Here is a better picture of it.



If anyone in the Vancouver wants some it has grown on to some shells in the substrate.
