Corys Not Cleaning

[pie]

I have 3 cory cats but there is still a ton of algae and they don't clean the gravel.what's wrong!

err corys don't eat algae. they will eat food which falls to the bottom so make a good clean up crew but they should still be fed sinking pellets. If you want something to eat algae try a few otocinclus or a bristlenose plec.
