lol. I ninja'd your post.
IME, otos produce way more waste than a normal fish their size. When I first bought mine, I thought, ok, they're tiny fish, so it'll be a small bioload. I put 6 at once in QT, using a cycled filtered pad, and they still managed to cause a mini-cycle.
The thing is, because they're eating only algae and the microscopic biofilm that we can't even see, they have to eat a LOT of it to stay healthy. So basically they just eat and poop all day long
