Can Someone Please Help Me Identify????

[Cory-girl]

I purchased my first Coral 2 weeks ago. It is doing really good. But tonight I found this green thing underneath the my Coral. I have no Idea what it is, or even if it can hurt my coral.

I am new to the hobby and I have never seen anything like this. Please help, I don't want to lose my coral!!!!!!:too_sad:

From what I can see on my phone it looks like a sponge. Harmless unless they get out of control and grow over the coral.

she's right, it's just a sponge... harmless....

Thank you for helping me id this thing. It scared the daylights out of me!! Right now it's below the coral but a few of the branches are growing right on the sponge.
If it does continue to grow and invade my coral what can I do?

If you can take put the coral, the sponge should be easy to pull off or scrub off with a hard bristled tooth brush. Rinse it off with tank water in a bucket before you put it back in the tank.

I believe most sponges will die if exposed to air thats what ive always heard. So if it starts to get outta control you could probably pull the rock out for a min and that will take care of it

Leave it. natures filter. It's harmless.

Thank you all for the input. I have watched it carefully for the last two nights. It seems to inflate at night, almost like a balloon. My coral is doing good so I am not to worried. I know look for it whenever I view the tank. I will take miyags advise and leave it be. If it does get out of hand I will have to get rid of it. For now it's become a focal point in the tank.
