Hello, i have recently stocked my 120 with the following: a 5" red devil, 5" jack dempsy, 4" texas, and a 7" red terror. I also want something like a loach or small catfish that will clean up a little more than it makes a mess. Suggestions are greatly appreciated on the loach thing. So anyways do you all think that my tank is overstocked? Thank you all so very much.:help:
