Is this fungus?

[Chrisq0904]

Ive noticed this white slime looking thing growing on my acan and something similar on my gsp. Is it some sort of fungus?

Looks like some kind of sponge

That's really good to hear!! I was getting worried. Could this also be why my acans look so bad?

With the acans under the same lighting as your SPS in that photo, they might be getting too much light. Acans do best under lower lighting and moderate flow. Also do well with being fed frequently.
