I want to add a few different species of Plecos to a 75gal tank. I have heard several different answers on this, some say "no" and others say they won't attack anything else in the tank except each other. Can I get some real life experience on this please. My plan is to add: (1) Gold Nugget, (1) Sunshine and (1) Royal. I will eventually, within 6 months, have my 175g up and running. Just have to finish the room I am working on in the basement.
