Seahorse Care and Seahorse Tank Set Up

One of the main reasons why people want to start a saltwater aquarium is to have a beautiful tank full of Seahorses. These delicate fish and intriguing and each one has its own personality. If you are new to the hobby or thinking about starting a saltwater aquarium, please take some time to research Seahorses before making a purchase. To learn the basics of marine aquarium husbandry, consider setting up a Fish Only or Reef Aquarium first; this will greatly improve your chance for success!

Do You Have the Proper Seahorse Tank Set Up?

1. The aquarium has already cycled and there is no detectable ammonia or nitrite. Nitrate Levels should be at a constant 10ppm or less. Other aquarium water parameters should be kept at optimum levels.

2. Unlike most fish, Seahorses are active vertical swimmers and require an aquarium at least 20 inches tall. Depending on the size and species, approximately 1 Seahorse can be kept per 5 gallons of water. You may need to purchase an aquarium labeled High or Extra High. For Example 20H or 20XH.

3. Seahorses will not do well in Reef Tanks where they can be stung by some most corals and turbulent water flow will makes it difficult for them to feed, swim and hitch.

4. Seahorses will not do well in Fish Only Tanks where large, aggressive fish will steal their food and even eat them. Generally, aggressive fish like Damsels, Lionfish and Triggers do not make good tank mates.

5. Seahorses also require a hitching post. A hitching post is a structure that a seahorse wraps its tail around. Gorgonians and other Sea Grasses like Caulerpa make ideal hitching posts for most Seahorses. The different macroalgaes will also provide filtration, but should be no substitute for a Protein Skimmer and water changes. Although Seahorses do not need light to survive, different Gorgonians and Sea Grasses may require intense light and feedings. Artificial plants and corals also make a good substitute.


Do You Have the Time to Take Care of Seahorses?

1. Each Seahorse should be fed a small portion of Mysis Shrimp 2 to 4 times per day. Yes, these fish require multiple feeding per day.

2. In the beginning, Seahorses may be extremely finicky eaters and will need to be target fed. They may need extra attention and care until they begin to actively hunt food.

3. Any leftover food should be siphoned out of the aquarium if a clean-up crew is not present.
