Good or Bad: Polyps or something?

amhealy · #1 May 5th, 2007, 05:11 AM

Hello everyone. I don't know if I have a problem or not, but there are some things growing all around my tank. The are mostly in clusters, they don't move around, they are stationary. They are small, but growing. Here is a pic of some of the larger ones growing at the base of one of my flowerpot coral: http://www.amhealy.com/aquarium/Coral.jpg

Does anyone know what those are? The other day I turned a rock over and found them growing on the flip side, in a cluster. I have spotted a few here and there in other parts of the tank.

Good or bad??? Thank you!!

looks like sponges to me. if i am right, then they are good.

Thank you, but what's a goni??

Look like sponges to me.Maybe a slight chance its a tunicate.Both harmless.
Is it or something else causing the Goniopora(Goni,Flowerpot) to be retracted near the bottom?

It's a pinapple sponge, they are harmless and good for your tank because there filter feeders. I have these all over my tank on all the rocks, they seem to spread very fast.

i don't think that those sponges are causing the goni(flowerpot) to retract like that. it has to be something else.

I didn't think it was the sponges either,looks like it could be starving or simply be retracted from being touch.

i think something is touching it. are there any corals close to it that could touch it? if so, you might wanna move it away.

First, thank you everyone for taking time to help me. I didn't know that the retraction was a bad sign. I never noticed that before. What should I do??

I test my water weekly and usually do a 10-gallon water change every weekend.

I did recently lose 2 anenomes. I believe it is because one of them looked large and old, and the other one always looked a little funky..it would sort of shrivel on different parts and almost look burned.

At one time I was probably feeding them too much. Right now I feed the fish 2 or 3 times a day with the Mysus shrimp.
