Apogon nematopterus (Apogon pajamas)

The Apogon Nematopterus fish is a fish from the Apogonidae family, also known as the black-tailed cardinal fish. It is a marine fish that lives in coral reefs of the Indian Ocean and the Pacific Ocean.

The Apogon Nematopterus fish has a fairly distinctive appearance, with an elongated body and a dark gray-green back and a lighter belly. Its head is small and sharp, with round eyes and a mouth located at the lower end of the body. Its dorsal fin is long and sharp, while its caudal fin is rounded.

The Apogon Nematopterus fish is about 10 centimeters in length, although some individuals can reach a slightly higher size. It feeds mainly on small crustaceans and plankton, which it captures using its fins to quickly move into the water.

Apogon Nematopterus fish is a gregarious fish and tends to live in large benches. It is also very territorial and can become aggressive towards other fish approaching its territory.

Apogon Nematopterus fish is a protected fish in certain places due to its popularity as aquarium fish species. However, it is also threatened by the destruction of coral reefs and human activities such as fishing and tourism.

Possible in aquarium, provided that the apogoons are placed in a specific tank. Oral incubation seems to be ensured by the male. Unfortunately, breeding - and in particular the food of fry - remains problematic. No success has been reported to date.
