I need some help with the ID of this sponge please. These few have not spread much, but seem to have grown a little.
It is attached to the rock base of a very large unknown Sarcophyton. I'll post pics of that toadstool at another time in the hopes of getting an ID as well. I need to get good pics of it.

Looks very interesting - totally random but I uploaded the picture into Perplexity Pro to see if it can identiify it. This is what it said, curious what the real answer is though.

Thanks for sharing that. I've never tried Perplexity. I appreciate the insight. I'll plug in that genus and species and see what more I can learn.

Although, it definitely does not have the ball shape indicated by the pictures of that species.
 
Looks kinda intreststing. Cool in someways long as it doesn't become invasive. I have yellow stringy sponges in my tank. Has stayed in one spot over the last year and half so hasn't really bothered me.
 
My black sponge grows more blob like than your silo like towers. Maybe just different stages of growth but same type? It has been in the tank for several years and grown at a slow rate and mostly in shaded areas.Slow enough that I have let it ride.

Here is a pic from the web that shows similar blob like growth to mine:

That's the kind I had on my old rock, very slow growth like you said.
 
very slow growth
I agree with this. Very slow growth. I'm not concerned about it taking over. I'm intrigued and would prefer to keep it alive the best I can. It is currently only shaded by the structure of the large toadstool. It doesn't seem to mind that it gets quite a bit of light. Would it be better to try and put it in the sump area instead? Or just leave it?

Don't expose it to air if it's something u wanna keep. Container it under water. I heard Air kills some sponges immediately.
