Im debating going with a 90 gallon Discus tank vs pairing up some RD and Kamfa flowerhorns. With that being said how hard is it to maintain a Discus tank? Obviously I know you have to keep temp higher but Ive heard they are much more delicate fish and take as much care as a salt tank. I was thinking that if I go with Discus in my 90 maybe 3 checkerboard pigeon, 3 blue sapphire, and 3 of a darker color... Any thoughts or suggestion?
