Soon I am getting a 55, a 40B, and a bunch of 10's and 20's from a friend of mine. I want to set up a aquaponics system with plants in the 40B and fish in the 55. My question is what fish should I stock in the 55? I have a 55 now with an Oscar, a 30 with a turtle, and a 20 with guppies, a pleco, and a dojo loach. I need ideas on what to put in this new 55 I will be getting. I prefer fish that are more simple to keep, not a fish that's gonna need super specific PH and all 24/7 but would go the extra mile for a nice looking tank as well. :
