Nerite's Effectiveness as an Algae Eater

[frothhelmet]

So I have a newly set up 20l nano and I got a couple Nerites to clean up the glass which really got hit hard. But check out what a champ my Zebra Nerite is in this photo. He did all of this in less than 24hrs.

Strangely, my tracked Nerite doesn't seem to be as effective, it is smaller though...

Nerites are my algae of choice. if only they didn't lay those annoying eggs!
