Have some red gracilaria I need to clear out of my refugium, not sure if technically dragons breath variety but nice red color and grows quick. In Newton.
Chaeto is better in nutrient export. Dragons Breath doesn’t do much but it’s pretty nice to have, except the part where they fall off and fly everywhere. They are tougher to mount. I have some.
I’ve had good luck with Gracilaria for export too. They do beak off sometimes but the pieces seem to be bigger than tiny chaeto wires. And I find it’s less finicky with light levels or flow. But to each their own
