Your best bet would be Nemos, however I would advise against any Linckia species besides multiflora (which Nemos still has I think). Most ornamental stars aren't worth the risk due to improper handling, exposure to air damages their hydraulics and they never recover fully. Sifter stars are the same, Pure Reef throws them out if there's air in the shipping bags because they almost never survive.
Some stars, like L. multiflora and chocolate chips, are intertidal and can withstand being out of water. same goes for brittles and serpents. I've had luck with the imposter 'red Linckia' (actually a Fromia) in the past as well if you can find one of those, but blues have always withered for me.
TL, DR: Not worth $40 to watch it melt, go for multiflora. Best Asterina eater that won't touch your urchins or cukes.
