Sponge ID

[79chopperdr]

I have alot of this sponge growing in my tank. It starts under the rocks white and grows out in the open with these long thin fingers, turning gray to black.

Some acros are STNing where contacting the sponge.

Id like to ID the sponge and a predator for it.

Thanks

Disclaimer... The picture is stolen, but identical to what I have.

Can't see any texture of the sponge so my guess would be Callyspongia tenerrima (base on the color, shape and grow form). I don't know what will eat it.

@dzhuo, thank you for the name. It led me to some good research sites. These look even closer to me. If I was to get a picture, is the a specific area you would be intersted in seeing?

Haliclona fistulosa

Haliclona koremella

Haliclona twincayensis
