Awesome! love the reponses guys!

#1 - I'll keep the sponge, thats a neat thing. Should I "feed" it at all?

#2 - Just stabbed 'em with the Chem-Marine Aiptasia stop, hopefully that will work for them.

#3 - About to kill it but wanted to double check. The picture looks a bit brown but he's really a purple colour..... and I thought Aiptasia was a bit transparent? He's definatley not.

Any thoughts?

-Thanks

#3 is definitely aiptasia.

Sponges move around the tank?

[EndlessHarm]

try peppermint shrimp it worked in my take to kill my aiptasia

[Funkytone]

Thanks for all the input!

Aiptasia and Majanos are dead/dying and besides the mushroom I have, the pineapple sponge is the second addition to the tank.

Thanks

So these pinapple sponges - do they have little round indentations all over them, too, kind of like craters in the surface of the moon?

I lost a really nice colt coral, and this big round thing was at the bottom of it. I thought it was just a piece of the colt, but now an exact, smaller replica has appeared several inches away from the first. From your picture I cannot tell if it has the craters, though.

Yes it does have craters. Really small though and no pattern to them just sporatically around it.
