Kuda Seahorse
Hippocampus kuda Bleeker, 1852
Also called Spotted seahorse, Common seahorse, Estuary seahorse, Yellow seahorse
From Indo-Pacific, from southern Africa and the Red Sea to Hawaii and French Polynesia, north to Japan and south to Australia. Aquarium fish are usually captive-bred.123
At a glance the quick version
Wild fish 17 to 30 cm (maximum 30 cm total length); aquarium fish reach about 15 cm (6 in).
Looks how to spot one
Bony-plated seahorse
A smooth-bodied seahorse without prominent spines, with a fairly large head, a short thick snout and a small coronet. It is often dark with a grainy texture, but can also be yellow or cream, sometimes with reddish blotches and fine dark spots.2
Personality what they are like
Peaceful and calm. Pairs court with colour changes and coronet clicking, and adults are often seen in pairs.213
Daily activity how busy a day looks
A slow swimmer that spends much of its time hitched by its tail to branching rock, plants or decor.23
Grooming and care the hands-on bits
Rated difficult. Remove uneaten food and debris daily, keep water quality high and monitor calcium and alkalinity. Keeping the temperature at the cooler end of the range suits it well.3
Home where they are happiest
A species-focused aquarium of about 115 litres (30 US gallons) for one pair, plus about 38 litres (10 gallons) per additional pair, with gentle flow and plenty of hitching posts. Water about 22 to 26 °C (ideally around 23 to 24 °C), pH 8.1 to 8.4, specific gravity 1.020 to 1.025.32
Food basics what goes in the bowl
Frozen mysis shrimp and other small foods offered several times a day (about 4 to 5 meals). In the wild it suction-feeds on zooplankton and tiny larval fish.321
Company who they like around
Best kept in pairs or small groups in a calm tank without fast or pushy fish, or stinging corals.3
The story where it all began
Pieter Bleeker described the species in 1852. It is one of the best-known seahorses in the aquarium hobby and is now widely captive-bred.13
