In my 10 gal I currently have an otto cat in there. Great little fish except they don't like to keep the gravel clean. In the past I have always had plecos and then trade them in when they get to big for this size of tank.
I thought the otto would keep all clean but it has not done so. So I need to add a cleaner and was wanting to know which would do the "best" job at keeping the gravel clean??
Pleco or Cory Cats?
