Could be, but I have sen the work on cler glass when there was (I'll
admit it) a variety of algae present elsewhere.  Upon further
reflection, I suppose my original comment wasn't well thought out. 
Better to have asked:

What are they attracted to eat -- instinctively or -- god bless their
little brains -- cognitively?
What provides them their needed nutrition?

It occurs to me that algae might not figure into either answer, or one
or both.

Do cat(fish) get hair (algae) balls?
