The Seahorse is a fascinating aquarium specimen that is sought after by many hobbyists. There are about 35 known species in the wild and all of the species numbers are dwindeling due to commercial fishing and medicinal purposes in the Far East. People use Seahorses as medicine for nearly every common ailment under the sun in the Far East. Because of this practice and because they can be difficult to keep, they are only recommend for the advanced and committed saltwater hobbyist.

In the wild the Seahorse primarily feeds on crustaceans and small shrimp. In the home aquarium this diet can be difficult to maintain. Many that are kept in home aquariums often perish from malnutrition, starvation or fish disease brought on by these triggers. Feed them often with live fish food such as brine shrimp, mysis shrimp and vitamin enriched frozen foods. They are slow eaters that must be fed often, usually 2 to 3 times per day. Since they are slow eaters it is best to keep them in a species only tank so they don't have to compete with the faster swimming fish for the food.

Commercial breeders are having some success with tank raised seahorses. If you can find a tank raised specimens they will probably cost a little more but it will definitely be worth it. Tank raised specimens should readily accept frozen foods and they should be more hardy and less stressed than those collected in the wild.

Seahorse Comments

From: Dave
I keep my seahorses in species only tanks to avoid the food issues. They need to be fed multiple times per day (like 3 small feedings) and will not make it for long if they have to compete with fish day in and day out for their food. The fish are just way too fast. Mysis is one of the best foods you can give your captive seahorses. Also keep plenty of things for them to wrap their tails around (rock work) and keep the water clean by doing weekly water changes. Watch out for those filter and power head intakes! The water movement shouldn't be that high in the tank where this could be an issue, but just in case...
