Ha thank you for thinking of the theme! Starry works for sure. I was actually looking at a Midas Blenny like @Blopple is seeing success with (dragons like gold right?). Any opinion on Midas vs Starry?White light spectrum has more spectrum than what corals can use. The more white you have the more algae will readily grow. Now that you have algae growing though, consider adding a Starry Blenny or (if you don't want SPS) go with a Black Sailfin Blenny. Either should be great with your Dragon Theme. The Starry gets bigger though I think. A Hector's Goby or Court Jester is another good option that stays smaller but may not fit with your desired theme as readily.
