Info
Leach, 1814
Distribution:
Indo-Pacific: southern India to Japan, Australia and Tahiti. International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.
Biology:
Inhabits gravel or sand bottoms around shallow reefs, muddy estuaries and near mangroves, tolerating brackish waters. Ovoviviparous.
The male carries the eggs in a brood pouch which is found under the tail.
Synonymised taxa:
Hippocampus dahli Ogilby, 1908
Hippocampus kampylotrachelos Bleeker, 1854
Hippocampus lenis De Vis, 1908
Hippocampus manadensis Bleeker, 1856
Hippocampus mannulus Cantor, 1849
Hippocampus planifrons Peters, 1877
Hippocampus takakurae Tanaka, 1916
Feeding intake.
The fish take a long time to eat at the beginning, before the food is taken up, a close inspection is carried out. After acclimatisation, the offered frozen food is eaten without problems. It should be noted that wild-caught fish behave differently than offspring when it comes to food intake. In the case of offspring, the size of the fish purchased also plays a role in the choice of food.

The term "reef safe" is often used in marine aquaristics, especially when buying a new species people often ask if the new animal is "reef safe".
What exactly does reef safe mean?
To answer this question, you can ask target-oriented questions and inquire in forums, clubs, dealers and with aquarist friends:
- Are there already experiences and keeping reports that assure that the new animal can live in other suitably equipped aquariums without ever having caused problems?
- Is there any experience of invertebrates (crustaceans, hermits, mussels, snails) or corals being attacked by other inhabitants such as fish of the same or a different species?
- Is any information known or expected about a possible change in dietary habits, e.g., from a plant-based diet to a meat-based diet?
- Do the desired animals leave the reef structure "alone", do they constantly change it (boring starfish, digger gobies, parrotfish, triggerfish) and thus disturb or displace other co-inhabitants?
- do new animals tend to get diseases repeatedly and very quickly and can they be treated?
- Do known peaceful animals change their character in the course of their life and become aggressive?
- Can the death of a new animal possibly even lead to the death of the rest of the stock through poisoning (possible with some species of sea cucumbers)?
- Last but not least the keeper of the animals has to be included in the "reef safety", there are actively poisonous, passively poisonous animals, animals that have dangerous biting or stinging weapons, animals with extremely strong nettle poisons, these have to be (er)known and a plan of action should have been made in advance in case of an attack on the aquarist (e.g. telephone numbers of the poison control center, the treating doctor, the tropical institute etc.).
If all questions are evaluated positively in the sense of the animal(s) and the keeper, then one can assume a "reef safety".
