Common name: Bleeker's Lionfish

General Information

The Bleeker's Lionfish or Cockscomb Lionfish, scientifically known as Ebosia bleekeri, is a fascinating marine species belonging to the family Scorpaenidae, commonly referred to as scorpionfishes. This species is native to the Indo-Pacific region, with a distribution ranging from southern Japan to Hong Kong, and extending to Australia, Taiwan, China, and Korea.

This species is sexually dimorphic, with males showcasing elongated, curved bony crests on the top rear of their heads, while females have a low spiny ridge. The males also exhibit yellowish to orange median fins, whereas the females' fins are reddish. These unique features make the Bleeker's Lionfish a visually striking addition to any aquarium.

Care

Bleeker's Lionfish are best suited for experienced aquarists due to their venomous spines and specific care requirements. They thrive in tanks that mimic their natural silty sand or mud-bottom habitats. A tank with a minimum volume of 300 liters is recommended to accommodate their size and territorial nature. The tank should include ample hiding spots and a sandy substrate to replicate their natural environment.

Stable water conditions are crucial for their well-being. Regular water changes and a robust filtration system are essential to maintain water quality.

Diet and Feeding

In the wild, Ebosia bleekeri preys on small fishes and crustaceans. In captivity, they should be fed a carnivorous diet consisting of live or frozen foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Feeding should occur once or twice daily, with portions adjusted to avoid overfeeding and maintain water quality.

Behavior and Compatibility

The Bleeker's Lionfish is a solitary and territorial species. It is generally peaceful towards other tank mates but may exhibit predatory behavior towards smaller fish and invertebrates. Therefore, it is best housed with similarly sized, non-aggressive species. Due to its venomous spines, caution should be exercised when handling or maintaining the tank.

Reproduction

Breeding Ebosia bleekeri in captivity is challenging and rarely achieved. They are oviparous, with females laying eggs that are externally fertilized by males. The eggs are then left to develop independently, making it difficult to rear the fry in a controlled environment.

Health and Common Issues

This species is relatively hardy but can be susceptible to common marine ailments such as ich and bacterial infections if water quality is not maintained. Regular monitoring and prompt treatment are essential to ensure their health. Additionally, their venomous spines pose a risk to handlers, so proper precautions should always be taken.

Habitat

In their natural habitat, Bleeker's Lionfish are found at depths ranging from 50 to 220 meters, primarily on silty sand and mud bottoms. They are adapted to tropical waters and prefer environments with minimal light and moderate water flow.
