Lythrypnus dalli (Catalina Gobie)

The Lythrypnus Dalli is a fish from the Gobiidae family, originally from the coastal waters of the North West Pacific Ocean. It is commonly known as Allen or Blue Fish-Fish Fish, due to its lively blue coloring and its many iridescent scales which make it particularly lively and radiant.

The Lythrypnus Dalli is a small fish, generally measuring between 5 and 7 centimeters in length, with an elongated and tapered shape. His head is small and sharp, with round and expressive eyes, and his mouth is equipped with tiny and pointed teeth, perfect for catching the small prey he hunts in the seabed.

The Lythrypnus Dalli is mainly dark blue, with a lighter shade on the belly and bright orange spots on the sides. These spots are particularly visible in males, who use them to attract females during the breeding season. The Lythrypnus Dalli also has many iridescent scales that shine with a silver or golden radiance when exposed to light.

The Lythrypnus Dalli is a very active and mobile fish, who likes to move in benches to hunt and eat. It feeds mainly on small crustaceans and molluscs which it finds in the seabed, but it can also eat plants and algae. The Lythrypnus Dalli is also able to jump out of the water to catch flying prey, such as insects or small fish.

The Lythrypnus Dalli is a fish much appreciated by aquariophiles because of its bright color and its active personality. However, it is important to maintain it in a sufficient aquarium to allow it to move freely and eat properly. It is also important to maintain clean and well -filtered water to avoid diseases and infections.
