I did get 2 nerites a couple weeks ago. I've heard Otos won't do well in a new tank, so held off on them.
So you think this is some form of algae?
\ I had a before and after nerites post of my 10 gallon when it was first cycling. I had diatoms and algea on my plants and apple snail. My nerites ate (cleaned) the algea right off the apple/mystery snail 2!
