General information

The Tub Gurnard, Chelidonichthys lucerna, is a fascinating species known for its vibrant pectoral fins which, when spread, resemble the wings of a bird. This bottom-dwelling fish is not only admired for its unique appearance but also for its ability to 'walk' along the seabed using its modified pelvic fins. The Tub Gurnard is a member of the Triglidae family, which are commonly referred to as sea robins or gurnards.

Care

Tub Gurnards are not a common sight in home aquariums, primarily due to their large size and active nature. They require a spacious tank with a sandy or muddy substrate to mimic their natural habitat. These fish are carnivorous and should be fed a varied diet consisting of meaty foods such as shrimp, squid, and small fish. It's important to ensure that the aquarium is equipped with a tight-fitting lid, as Tub Gurnards are known to be strong and capable jumpers.

Reproduction

In the wild, Tub Gurnards spawn during the summer months. However, breeding them in captivity is quite challenging and rarely achieved by hobbyists. They exhibit external fertilization, where females release eggs into the water column to be fertilized by males.

Habitat

Tub Gurnards are found in the northeastern Atlantic Ocean, from Norway to Senegal, including the Mediterranean and the Black Sea. They inhabit sandy and muddy bottoms, often at depths ranging from shallow waters to about 200 meters. These fish are benthic feeders, using their 'whisker-like' barbels to detect prey hidden in the substrate.
