Hypseleotris leuciscus

The Golden-spotted Gudgeon, also known as the Chinese Gudgeon, is an active and engaging freshwater fish from Asia. With a sleek, torpedo-shaped body, it is a fast and lively swimmer that primarily occupies the middle and bottom levels of the aquarium. This is a social species that thrives in groups, so you should always keep them with several of their own kind to see their best behavior. While they school together, they can also be a bit territorial and chase each other, which is a normal part of their interaction.

Setting up their home involves an aquarium with gentle water movement, as they dislike strong currents. You can use plants and decorations like wood or rocks to give them places to explore and claim as their own. Because they are active and can be boisterous, they are best kept with other robust fish of a similar size that won't be easily intimidated. Avoid slow-moving or very small tank mates. Feeding is straightforward; as omnivores, they are not picky and will eagerly accept high-quality flakes and pellets, but they especially love treats of frozen or live foods. Due to their territorial nature and need for specific water flow, they are considered a 'medium' difficulty fish, making them a great choice for aquarists who have some experience and are looking for a fish with a lot of personality.
