Dude amazing tank and fish do look incredible with the black substrate!! Your Jag does look small in the tank.Quick question Does you jag leave all the smaller fish alone and is he super aggressive. Are you sure it`s not longer than 15inch`s, just asking cause my Jag gotta be min 15 inch but not nearly as thick and i wanted to put him in my 655g with all my loaches,arrows, green terrors and oscar,Thai silk FH he`ll leave them alone in such a big tank right??? What are your demensions on the tank mine are 10ft by 42in wide and 30in length. Your Old green terror inspires me to get more green terrors(RIP), I already have 13 of them and I got 2 that might be as nice as yours in the future. Sweet fish and would love to see more pics
