The dwarf seahorse only reaches up to 2 inches (51 mm) in length and is not an aggressive feeder. Therefore, it is typically kept in small aquariums (5 to 10 US gallons (19 to 38 L)). The dwarf seahorse can be fed brine shrimp nauplii, although it will also eat copepods and other shrimp larvae. Because of its short digestive tract, food must be ...
Seahorses should be kept in an aquarium with low flow and placid tank mates. They are slow feeders, so fast, aggressive feeders will leave them without food. [53] Seahorses can coexist with many species of shrimp and other bottom-feeding creatures. Gobies also make good tank-mates.
The short-snouted seahorse (Hippocampus hippocampus) is a species of seahorse in the family Syngnathidae. It is endemic to the Mediterranean Sea and parts of the North Atlantic, particularly around Italy and the Canary Islands. In 2007, colonies of the species were discovered in the River Thames around London and Southend-on-Sea. [4]
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 Pacific seahorse, also known as the giant seahorse, (Hippocampus ingens) is a species of fish in the family Syngnathidae. Their genus name (Hippocampus) is derived from the Greek word hippos, which means "horse" and campus, which means "sea monster." [4] This species is the only seahorse species found in the eastern Pacific Ocean. [5]
Hippocampus kuda is a species of seahorse, also known as the common seahorse, estuary seahorse, yellow seahorse or spotted seahorse. The common name sea pony has been used for populations formerly treated as the separate species Hippocampus fuscus , now a synonym of H. kuda .
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.
In species where males take on more of the reproductive costs, such as sea horses and jacanas, the role is reversed, and the females are larger, more aggressive and more brightly coloured than the males. In hermaphroditic animals, the costs of parental care can be evenly distributed between the sexes, e.g. earthworms.
