Acanthopsis choirorhynchus

The Horseface Loach, also known as the Long-nosed Loach or Banana Fish, is a fascinating bottom-dweller named for its distinctively long, horse-like snout. Its most famous behavior is completely burying itself in the sand with only its eyes showing. This is a natural way for it to feel safe and rest. Because of this, a soft, fine sand substrate is absolutely essential in its aquarium; gravel or sharp sand will injure its delicate face and barbels, leading to infections. These are not solitary fish. They are social and feel stressed when kept alone, so a group of at least five is necessary to see their natural, active behaviors. When comfortable, they will playfully chase each other and explore the bottom of the tank. An aquarium for a Horseface Loach must have a tight-fitting, secure lid. They are surprisingly powerful and are known to be skilled escape artists, capable of jumping out of the smallest gaps. As a bottom feeder, its diet should consist of foods that sink. High-quality sinking pellets and wafers make a good staple, supplemented with treats like frozen or live bloodworms and brine shrimp. They are generally peaceful and can be kept with other calm fish that occupy the middle and upper levels of the tank, such as rasboras and tetras. Due to its specific sand and group requirements, it's best for aquarists with some experience.
