I had these guys in with my fronts but I had to move them bcs they were way too territorial and were only allowing the fronts to have 1/4 of the tank! I am planning to give them their own tank asap!
I think I will be putting these guys in the 180 along with the fronts.....I think they will have a harder time taking over the whole tank when it is 180 gallons as apposed to the 50!!! lol!
