Hi, What's a good brown algea cleaner for the substrate?

[Florida8]

There isn't much, but some ... mystery snail or some other bottom dwelling fish?


... also this is a small 7.5 g bow... so I need something smaller.

Thanks!!!

Otocinclus cats eat brown algae.

I've found that it eventually goes away on its own as the tank matures, but will reappear if you add new substrate or rocks.
