algea help!!

If your bioload weren't maxed out I'd suggest a baby pleco. Mine has eaten every trace of brown algae and keeps it up even though I feed him plenty of other food. But three goldfish in a 55 is pushing it already, so if you add anything, get rid of the snails first. And only put a baby plec in if you're prepared for a really big tank in a year or two and are an obsessive water changer. Good luck!

P.S. If not well-fed, plecos have been known to suck on fish, killing them, so veggies, wood and wafers aplenty.
