Common name: Short siphonfish

General information

The Cardinalfish with Tubular Eyes, scientifically known as Siphamia fistulosa, is a fascinating species of cardinalfish that is not commonly found in the aquarium trade. This small, nocturnal fish is known for its unique tubular eyes, which are adapted to enhance its vision in low-light conditions. The species exhibits a silvery body with a translucent quality, allowing some of its internal organs to be visible, which adds to its exotic appeal.

Care

Siphamia fistulosa requires a specialized care regimen due to its nocturnal nature and sensitivity to light. Aquariums housing this species should provide dim lighting or areas of low light to mimic their natural habitat. They thrive in a peaceful community tank with plenty of hiding places and a sandy substrate. It is essential to maintain high water quality and stable conditions to keep these fish healthy.

Reproduction

Like many cardinalfish, Siphamia fistulosa is a mouthbrooder. The male carries the fertilized eggs in his mouth until they hatch, providing a safe environment for the developing embryos. This reproductive strategy is fascinating to observe and can be a rewarding experience for dedicated aquarists.

Habitat

Siphamia fistulosa is typically found in shallow reef environments, often associating with sea urchins or branching corals for protection during the day. At night, they venture out into open water to feed. Their natural range extends across the Indo-Pacific region, from the Red Sea to the Western Pacific Ocean.
