The Yellow Seahorse is one of the larger seahorses and is also known as the Common Seahorse, Spotted Seahorse, or Oceanic Seahorse. It has a short crown which is directed backward. Hippocampus kuda actually comes in many colors including yellow, orange, brown, and even black. In order to maintain the coloration of these wonderful animals it is ideal to keep décor of a similar coloration in the aquarium. Some individuals may have spots. It is difficult to keep in an aquarium. Tank raised specimens are currently available.
For the best results, seahorses should be kept in a separate, species-only tank that is 50 gallons or larger with multiple items which they can grab with their prehensile tails. The reason for this is that seahorses are very slow methodical eaters and when maintained with other fish, they will never receive the proper amount of food to thrive in the aquarium. The Yellow Seahorse reacts poorly to being harassed by other more aggressive fish such as: blennies, wrasses, tobies, triggerfish, and porcupinefish.
The Yellow Seahorse tends to get along with pipefish, but they are a slightly faster feeder than the seahorse so it is imperative that the aquarist offers the proper amount of food for the seahorse. The Yellow Seahorse needs a diet featuring live ghost shrimp, grass shrimp, opossum shrimp, amphipods, and other small crustaceans. It may accept vitamin-enriched adult brine shrimp, but not as a steady diet. It may often be trained to accept nutritious frozen foods such as mysid shrimp.
