jdiver Posted January 23, 2003 Share Posted January 23, 2003 In my 5 gallon nano the light is on stands so it is above the HOB filter. Because of that the output of the filter tends to get covered with algae that I usually pull off every week or two. It was pretty well covered and needed to be cleaned when I noticed an Astrea crawling up to it via the intake tube and over. He's been up there for 4 days and has eaten about 75% of the algae off. He's still up there, but wasn't moving most of yesterday, presumably because he was so darn full. Thought it was pretty amusing. Link to comment
