I also have a kind of off subject question now and don’t really want to start another thread unless it’s necessary. What are the best algae eater type fish that will pretty much eat only algae and of course other stuff as well. I have just a little bit of algae growth on my glass and thought if I could have a fish that would benefit from that it would be better than me just cleaning it.
 
The arch in its back makes it seem different from the serpent loach.
He arches it when he’s trying to find food when he’s sitting on his leaf he’s pretty much straight as an arrow. He crawls on the surface he’s eating on instead of facing down and digging around like say a yo-yo. That’s one thing why I think he’s so cool.
