I'm talking about the algae that you have to scrape off with a razor. I see them eating the algae when scraped off but I was wondering can they eat it off the glass. I figure I might just leave the back glass covered in it if they do pick at it.
i find green spot almost a necessity when the shrimplets are born. Its usually beneficial to have in a shrimp tank. If it gets a bit thick, i generally clean the front glass of the tank while leaving the sides and rear as is. G/L!
