I tend to keep my tanks fairly weedy and dirty, with lots of snails to clean up uneaten food and keep the algae and biofilm under control. Now I'm trying to keep a few tanks mostly sterile for angelfish I need a different strategy.

Do people keep scavengers in your grow-out tanks? If so, what kinds? I'd be happy to have a few schools of Corydoras but I've read conflicting reports about how well they do without sand to dig in.

All my Corydoras live in barebottom tanks. :) However, I do wipe the bottom surface of these tanks at least weekly, if not daily. Having said that, I have always done this with Corydoras and have never experienced any problem with fin or bristle erosion as have been predicted on the Internet. :D

Other scavengers that live in bare bottom tanks include all types of bristlenose and various L-number plecos. Again, it's never been a problem.
