Incubation period: 21 days
Spawning tank size (liter): 110 – 230 (30 – 60 gallons)
Sides of tank covered? beige or green
Lighting & photoperiod: 110 liter tank – 40 watts 10 – 12 hours per day (shortest during summer). 230 liter tank 100 watts. Photoperiod is the same as smaller tank

First food offered: Day 1 to week 3- Mixture of dry food and newly hatched artemias
Second foods offered: Week 3 to month 2 : hatched artemias and introduction of “cyclopes” = very little frozen food (I think these are copepods) newly hatched Artemia
Third food offered: Month 2 to month 5- Frozen adult Artemias (but only small specimen)
Fourth food offered: Month 5 to 1 year- Frozen and/or live Artemias and introduction of mysids (small specimen). After 1 year Artemias and mysids of all sizes.
Note: DO NOT FEED mysids before 5 months, unless the seahorses are a large species with large mouths!
Long term survival: 95% (2.5 to 3 years)
Development description: Color change during third and fourth month.
Original description: First described by J. J. Kaup in 1853 in Arch. Naturgeschichte v. 19 (no. 1), based on specimens collected near Japan. Most recently validated by Gomon, 1997.
Word origin: Hippocampus (Greek), a fabulous sea monster. hipp, -e, -o, =us, (Greek) a horse. camp, =us,(Greek) , a sea monster. It is unclear what the genus histrix is referring to, although this is not an uncommon “species” identifier.
