However, big-belly seahorses fed higher rations (10–20% of wet body weight) had greater body weights and higher condition factors. The most cost-effective feeding strategy, based on the total mysids offered, was the 5% ration, with survival rates remaining at 100% across all treatments.
Short snouted seahorses are considered ovoviviparous meaning that the female deposits eggs into a pouch on the males stomach, called a brood pouch, and the male goes through pregnancy and labour. [9] Sexual maturation occurs during the first reproductive season after birth.

[3] Seahorses spend most of their time anchoring to coral reefs and branches with their tails because they are poor swimmers.
