Hemiodus gracilis or Slender Hemiodus is a peaceful, somewhat shy schooling fish you can keep in a larger community aquarium. The aquarium should be planted densely on the sides and background. In the middle you should leave a lot of free swimming space. The fish needs a lot of oxygen, so you should use a strong filter. It is not a fish for beginners. He can be kept together with other peaceful fishes. It will take several weeks before they are accustomed in their new environment.
This species has been officially described by Günther in 1864.
