yeah i think i would only get one and he would be upgraded to a 150 gal next christmasGruff Master;4888367; said:I'm with Danger Chicken, don't plan on keeping a pair of Jags in a 90gal for life. I had a male Jag in my 120 that made it look more like a 75 after a few years. A small pair would work for a while but with their potential aggression and adult sizes, a much larger tank would be best.
