Hello everyone. I have always kept my plecs on gravel or barebottom tanks. Anyway, my 100g has an algea problem that I have been battling for a while with a razor and a mag float. I have some room in there since a fish died from getting cut on a dangerous decoration, and all thats in there at the moment are an 8" oscar, 6" severum, and 4" Geo. Steindachneri. My LFS has a stunning 8" royal pleco for 40$ and i want to pick it up tomorrow, but i was wondering if there is a problem with plecos and sand substrate? I doubt they can safely "suck it" without getting a sandy mouth. Is it safe?
