I don't know but I am going to try the same thing actually. Just need to try and get my trimacs to catch up to the Jag. Currently in seperate tanks. Either one could win just depends on personality and will to dominate. I would guess most likely the Trimac would win but the Jag I have now seems pretty mean Has half of a 125 to himself with 4 Red Terrors, vieja synspilum and a Butterkoferi. All about 3-4 inches
