Tank Raised seahorses are raised in net-pens overseas in the ocean. They are exposed to the same pathogens and parasites that wild caught seahorses are. Thus, they should be treated the same as wild caught seahorses. Meaning, dewormed and watched carefully in QT for 4-6 weeks.
IMO, the only advantage to tank raised over wild caught is tank raised are eating frozen foods. Other than that, they are the same.
Captive Bred seahorses have never been exposed to the dangers ocean water can carry. They have not been exposed to parasites, etc.
