The lined seahorse (Hippocampus erectus), northern seahorse or spotted seahorse, is a species of fish that belongs to the family Syngnathidae. [ 3 ] [ 4 ] H. erectus is a diurnal species with an approximate length of 15 cm (5.9 inches) and lifespan of one to four years.
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 20–28 °C (68–82 °F), with a pH ranging around 8-8.5. [12] The tank water must ...
Water quality is very important for the survival of seahorses in an aquarium. They are delicate species which should not be added to a new tank. The water parameters are recommended to be as follows although these fish may acclimatise to different water over time: Temperature: 23–28 °C (73–82 °F) pH: 8.1–8.4
A medium-sized seahorse, the tiger tail seahorse reaches a maximum total length of around 15 centimetres (5.9 in). [5] The coloration of this species is variable, generally being black or brown in adults with yellow saddle shapes on the upper surface and yellow stripes on the tail, hence the common name.
Pygmy seahorses are 14–27 millimetres (0.55–1.06 in) long from the tip of the tail to the end of the snout, so that their vertical height while swimming is still smaller. [5] An adult may be as small as 13 millimetres (0.51 in) long. [6] True pygmy seahorses have distinctive morphological markers. [5]
Adult seahorses eat 30 to 50 times a day if food is available; due to their slow consumption they must feed constantly to survive. [20] Big-belly seahorses do not have a stomach or teeth, so they feed by sucking small invertebrates in through their bony tubular snouts with a flick of their head. Their snouts can expand if the prey is larger ...
Photographs of seahorses taken by scuba divers revealed evidence of a long-lost species of marine worm that hasn’t been seen since the mid-1950s, scientists say. Long-lost ocean worms photobomb ...
The Hippocampus nalu's highly different spine morphology along the superior trunk ridge also differentiates the species from its fellow pygmy seahorse. [7] Being a pygmy seahorse, H. nalu is very small, with juveniles being ~10 mm long and adults growing up to a length of 2 centimetres.
