The Dartfish: the brave goby

The Dartfish, also known as Nemateleotris exquisita, is a species of fish that is native to the Indo-Pacific region. This fish is known for its unique shape and vibrant colors, making it a popular addition to many saltwater aquariums. However, it’s important to understand the specific needs and care requirements of this species in order to keep them healthy and happy in captivity.

The Dartfish is a small species, growing to a maximum size of about 3 inches. They require an aquarium of at least 30 gallons, as they need plenty of swimming space. These fish are known to be peaceful and can be kept in a community tank with other peaceful species. The water should be clean and well-filtered, with a temperature of around 72-78°F, a pH of 8.1-8.4 and a salinity of 1.022-1.025. It is important to maintain these water parameters to ensure that the fish are comfortable and healthy.

In terms of feeding, the Dartfish is an omnivore and will eat a variety of foods, including flake, frozen, and live foods. It is important to provide a balanced and varied diet to ensure that the fish are getting all the nutrients they need. However, it is important to keep in mind that these fish can be prone to obesity problems if given an inadequate or excessive diet.

However, they can be prone to common diseases such as marine ich and fin rot. If you suspect that your Dartfish is showing signs of disease, it is important to visit a veterinarian specializing in fish or consult with a professional from the website for proper diagnosis and treatment.

In terms of reproduction, the Dartfish can be bred in captivity, but it’s not an easy task. The best approach is to purchase a mated pair or a group of juvenile fish and provide them with a suitable breeding environment. It is important to provide a separate breeding tank with a temperature of around 78-80°F, and a pH of 8.1-8.4. The female will lay her eggs on a flat surface and the male will fertilize them. The eggs will hatch in about 3-4 days, and the fry will become free-swimming in about a week. To know more about breeding and rearing, you can visit the website
