I have a 6 by 3 by 2 tank (approximatively 250 gals) just finished cycling the tank for 1 month. I was planning on getting a pair of GT, i already have a common pleco(i know most of you don't like those). After that I was interested in some rope fish or polypterus and maybe some other cichlids. Will this setup work and what kind of other cichlids would work with GT's?
