I'll let the experts chime in on this one for sure. But, I would almost hazard a guess that you may need a chiller if you found this guy on an NC beach. I know the water doesn't typically get very warm. I imagine, too that it wil lbe need to be fed live food, being wild caught. I hear wild ones are hard to keep. I know theres a few good seahorse websites out there. Good luck!
