Kuhli Loaches are an eel shaped fish, with an elongated dorsal and ventral profile. They have a characteristic orange and black striped pattern along their body, which can range in intensity from faint to bold depending on the individual.

Kuhli loach fish are active and curious creatures, often exploring their tank environment and investigating any objects they come across. They display a unique behavior known as ‘bobbing’, in which they rhythmically rise to the surface of the water and then sink back down again. This behavior is thought to be used as a means of communication between them. In general they will be found at the bottom of the tank
Food and diet info
Kuhli Loaches are omnivores and should be fed a balanced diet consisting of both meaty and vegetable based foods. Kuhli loaches eat live food such as freshly hatched brine shrimp, black worms, daphnia, bloodworms, and other small invertebrates. Freeze-dried or frozen food versions of these foods can also be offered like frozen bloodworms, as well as sinking pellets and bottom-feeder tablets. Vegetables such as zucchini, cucumber, blanched spinach or lettuce can also be fed with a vegetable clip or feeder block. It is important to provide variety in order to ensure the loach gets all of the necessary nutrition that they require for optimal health.
Kuhli loaches are known to enjoy scavenging for snails, making them a popular snack food. Because of this fish's mouth being underslung, they have evolved to be well equipped for taking down hard-shelled prey such as snails. Snails not only provide protein, but also offer an additional source of calcium and other minerals. Kuhli loaches eat snails very effectively so adding them to rid your community fish tank of snails is a good idea! Knowing this your prized snail that you want to keep will not make great tank mates for kuhli loaches.
