Multiple sponges growing after deep clean of tank?

[Jorda320]

Hi,
I have a 2 year old 36 gallon tank. Recently I did a bit of a deep clean to it, I scrubbed all the rocks, and shook out the detritus, and basically caught up on maintenance. I adjusted the aquascape and the tank has been doing well since. When feeding this morning I noticed about half a dozen white fuzzy areas. They look like sponges but I would really like a second oppinion. Im a bit confused as to where they came from as I have not added livestock or corals since last summer, maybe even further back. Any thoughts? Also, the white mass on the torch protrudes out maybe 1/2 inch and is rounded like half of a sphere. Thanks in advance.

Sponges. Harmless but you can just pull them off if you don't like where they're growing.

Super, thank you for the info. Im always happy for an increase in the good biodiversity. Ill leave these little guys alone and see how things turn out.
