Basic Care Information


A 30 gallon aquarium is the minimum recommended aquarium size for a pair of our captive bred seahorses. An additional 15 gallons is recommended for every additional pair of seahorses. A larger aquarium is even better. Minimum aquarium height is 18 inches.  

Make sure your aquarium has plenty of “hitching-posts” for your seahorses to hold onto. Artificial branching coral or live Gorgonian corals are great hitching posts.

Seahorses do best in a species only aquarium without stinging corals, anemones, clams or aggressive fish/invertebrates.



Recommended temperature is 70-74F. Your heater should have a guard or be in a sump where your seahorses can not grab hold.



Seahorses need to be fed 2-3 times daily. We use both Hikari BioPure Mysis shrimp and PE Mysis shrimp. Either or both will work for you. Spirulina enriched frozen brine shrimp can also be fed as an ocassional snack to diversify your seahorse’s deit.

Uneaten frozen food should be removed from the aquarium after 30 minutes as it will begin to spoil.

IMPORTANT: Please make sure your saltwater aquarium is fully cycled before purchasing and adding your seahorses! If you have any questions about cycling your aquarium please contact us, we are happy to help.


Equipment and Maintanance

We strongly recommend having a good quality protein skimmer on your aquarium. Weekly 10-25% water changes are recommended.
