I have an IM30L AIO tank, with a small fuge in one of the rear chambers. the top of the fuge section gets light spill from the display lights during the day and gets lit by the fuge light at night. This stuff is growing on the top of the fuge section. Not showing anywhere else in the system (that I've found). I have a plan to clean it up and put a lid on the rear chambers to remove the daytime light spill but I'd still like to have a positive ID for what this is.

Cheers mate. Found this about it:

I gotta do some more sampling and microscoping. Man this hobby is cool.
