I am curious to know more about the algae eating habits of Central Stonerollers. What types of algae will they eat? Will they eat green film, hair, black beard, diatom, and blue-green algaes? Will they only eat algae off of rocks, or will they also eat it off of the glass, gravel, plants, and sand? Will they eat the plants in my tank?

My stonerollers eat the brown and green algae in my stream tank. It is planted heavily with American vallisneria and I have not witnessed them eating it or the algae that sometimes grows on them in spots. It is pretty obvious where they graze as there are cleared spots on the rocks as well as the glass.
Stonerollers are one of my favorite species to keep and I'd advise to start off with small ones as they adapt to captive life a lot easier.

My experiences are similar to Drew's. They will eat diatoms and various green algae from rocks, glass, and driftwood. I have not had black beard in the tank. The blue-green algae is confined to hidden pockets where the fish cannot get to it, so I assume they are eating it.
They will not wipe an algae-infested area clean as algae-eating catfish do. The stoneroller's mouth is designed to grab a bit of algae and tug it off, not to scrape a track through it. I can see J-shaped marks in the algae on the glass where the stonerollers have been feeding.
