Thinking of trying some flashers in the 80gal. Would a P. angulatus and P. cyaneus work in the 4ft tank or is 4ft going to be too small?Stick with the mysis for now, then when he’s with the big boys and more fish he’ll learn quickly. Mine all do, my Kaleidos is currently in a placid tank yet I bet once he enters the 5 foot with 2 others he’ll learn it’s time to get real
