Bad sponge

[dizzy]

I guess this could be included in the hitchhiker thread, but I didn't notice it for quite awhile. Anyway this blue sponge is growing on a rock from Bali. It had grown and attached itself to the piece of montipora cup in the second photo. I pulled it lose and noticed it had killed the montipora where it attached. Anyone know the species or anything about it?

No, I don't know what it is, but I used to have a tank that had an abundance of sponges identical in appearance to that.

i had a black sponge in my tank i had that same problem with. it made alot of finger like projections but would start to bleach the green monti cap i had it next to. i tried to remove it with some tweezers when suddenly i felt multiple stinging pains in my hand-- i can only compare the pain now to about 5-6 fire ant bites after having been bitten but at the time i didnt have anything to compare it to except OMG OUCH. IT STUNG ME! i yanked my hand out of the tank and though i had to remove its growth every few months to keep it away from my SPS i would wear rubber gloves from that point on whenever i worked with it. still there are so many species of sponges we know absolutely nothing about so if you were going to die from some weird disease unknown to science i think youd get it from some strange sponge growing on a piece of liverock first.

isn't it dangerous to put tweezers in your tank?

some will say yes, but as Ive done it countless times, I say no.

Just don't leave them in there and it will be fine.
