This is my boy Davy, he cleans the tank up real well and adds his own additional flare. I use sand substrate (purewhite silica sand) he poops a moderate amount that I can notice was bad when he was first introduced to the tank but has slowed down. However i also set up a dip in the sand and put drift wood over it to set up a deadspot in my tank that everything gathers in for extra easy cleaning and a better first apperance. Should be fine as long as you keep up with your regular water changes. I like him in planted tank most, eats competition, and turns it into neutriants for other plants.
