Okay well then I guess I may have to get the amanos, I just switched from sand as it was too deep and the plants weren't doing good. I don't want to put cories on gravel as I don't want them to injury their barbels. So i am left with nerite, amano, or otos.
The thing about nerites is that they can't fit onto tiny leaves, only glass gravel and large leaves. I think I have a small diatom problem- but my cories eat it like crazy. They love cleaning the leaves... But the hornwort is a piece of filth.
Would the ammonia build up? I know they are poop machines so yeah. I will see, I want some but if they die they are something I would have to get shipped again. Is their any other inverted or fish, besides otos, that eat brown algae?
