For my community 125g tank, what would I need for a good clean up crew (together with good filters) so that my cleaning maintenance is reduced? I will be getting more cory cats, but the new ones and the current ones are younger and only 1". I think I will have six, possibly willing to get a second group of six cory cats. The tank also currently has a 11-12" pleco but I am thinking of not keeping him. I have fake plants. Very natural gravel varying shapes and sizes from .1 inch to .6 inches that I really like having.
