The 2 orino are about 5-6" now and are with a 7-8" motoro. They're all in a custom 135gal (8'x1.5'x1.5'). When they're all big enough, all 5 bass and the ray will go in to the 600.Very nice! How big and want type of stingray are you keeping them with? I wanna add something to my 500gal w my trio of rays but they’re 12-17” so I prolly need pretty big tank mates
