Macroalgae ID help

This was labeled as Dragon's Breath when I got my hands on it, but after a month or two in my main display under intense lighting from my freshwater spectrum light it took on a very dense form like this. Grows in that less fluffy, more sharp-and-twisty way that dragon's breath is supposed to under 'typical' lighting. It's only under my freshwater spectrum that I've managed to get it to grow in this form.
Any ideas? I love it :)
