The Patagonian seahorse (Hippocampus patagonicus) is a species of marine fish of the family Syngnathidae. It inhabits coastal waters from northeastern Brazil to Chubut , Argentina . It generally is found at shallow depths attached to natural or artificial substrates.
They require taller tanks, live/frozen food, and many hitching posts, as well as very peaceful tankmates. In fact, beginners would be well-advised not to mix seahorses with any other species until they have more experience. Good tank mates would include other peaceful, microfauna consuming species such as pipefish and dragonets.
The big-belly seahorse (Hippocampus abdominalis) or pot-bellied seahorse [3] is one of the largest seahorse species in the world, with a length of up to 35 cm (14 in), and is the largest in Australia. [4] Seahorses are members of the family Syngnathidae, and are teleost fishes.
The seahorse fry can be kept in the same aquarium as the adults in a dwarf seahorse dedicated tank. The dwarf seahorse has a gestation period of 10–14 days and can live up to over 2 years in captivity. The water temperature in the aquarium must place between 20 and 28 °C (68 and 82 °F), with a pH ranging around 8–8.5. [12]
Male seahorses have a specialized ventral brood pouch to carry the embryos, male sea dragons attach the eggs to their tails, and male pipefish may do either, depending on their species. [4] The most fundamental difference between the different lineages of the family Syngnathidae is the location of male brood pouch. [ 5 ]
The lined seahorse is a diurnal species that ranges in length from 12 cm to 17 cm; the maximum length reported for the species is 19 cm. The seahorse is sexually dimorphic, meaning there are distinct differences in appearances of males and females; most notably the brood pouch located on the male's abdomen which it utilized in reproduction.
Many are very weak swimmers in open water, moving slowly by means of rapid movements of the dorsal fin. Some species of pipefish have prehensile tails, as in seahorses. The majority of pipefishes have some form of a caudal fin (unlike seahorses), which can be used for locomotion. [2] See fish anatomy for fin descriptions.
Hippocampus haema, the Korean seahorse, is a seahorse of the family Syngnathidae native to the northern Pacific Ocean (Korea Strait, Sea of Japan, northeastern coast of Honshu), and it usually lives in Sargassum and weeds on shallow soft bottom habitats from 0 to 18 m depth.
