black tail hemiodus

A medium-sized schooling tetra relative, the Red Tail, Red Line, or Slender Hemiodus (Hemiodus gracilis) is widespread throughout the Amazon and Orinoco basins, where it is usually found in large mixed species shoals alongside other schooling tetras. A fast and somewhat skittish fish at first, they make for an impressive display in a larger mixed species aquarium and make excellent tankmates for most other peaceful fish. This species prefers warm, slightly acidic water and will do best when given plenty of cover in the form of driftwood or tall plants.
