Need help with identifying sponge

I did a blind-buy of a sponge labeled as a "blue strawberry sponge" from my dealer and this is what I received. I tried searching for something similar but haven't been able to find any matches.

The photo is pretty representative of the color. Every 1-2 weeks, the "strawberries" or "flower" parts of the sponge float away, sort of like little cotton balls. I believe that's how it propagates but I have not found any new sponge growth anywhere in my tank yet.

Sponge experts, help me ID this sponge!

That's not a sponge, it is a tunicate. Looks like Nephtheis fascicularis which is sometimes called Blue Palm Coral.
 
Well, that explains why I've had so much trouble finding a match. Not sure why my dealer listed it as a sponge. Thank you for the ID!
