picked up a small lettuce nudi last week from an LFS
as I wanted one for a while. I do have different algaes in my nano reef so I figure there is going to be something in there it will like, hair included but Ive noticed the last couple days its actually hanging out at the top of my tanks back wall. I know there is brown (what looks to be) diatom on the glass but do they actually eat this? I have placed it gently back on the rocks and it will sit there and graze for a while on the hair and flat green algae (at least it looks like it is) but then move right back to the same area. My water parameters are fine, flow is not too high, in fact the spot its moving TO prob has the most flow of anywhere in the tank.
I wanted to see how well it held up before I got a second one, because I do really like them, but I wanted to know if this was normal behavior. Ive done a lot of research before getting one but always read they mainly go for hair and bryo algae not brown diatom.
also I know they dont actually EAT algae and literally suck out the cells for storage but I just say they eat algae or graze because its more broad.
