Will sponges take over a coral?

[Joshsmit56001]

I have a small rock with star polyps on it and there is also some sponge on the same rock. My worry is that it is killing my star polyps. Second, the same star polyps are connected to another rock but I want to move the main polyp rock somewhere else. Can I just cut the polyps where I want to or what should I do?

Thanks,
Josh

Certain sponges will live symbiotically with some coral types, primarily zoo's though. With GPS's they are both encrusting species and one will try to win out over the other. If that's the case, a soft toothbrush or a coral dip should get rid of the sponge.

Use a sharp exacto blade and cut along the seam between the two rocks. It will not harm them at all and you will end up with to colonies.

Whats a coral dip?

<<Coral Dips>> are basically disinfectants to help remove parasites and other problems. Just be sure to read the instructions carefully. Some coral types are not recommended. Personally I think the toothbrush is easier and the sponge should necros if exposed to air while doing so.
