Blue Gudgeon Dart Fish

  • Ptereleotris Dartfish should be added to well established aquariums with plenty of room to swim.

  • Plenty of rock work with caves, cracks, crevices and a deep sand bed should be provided for hiding and sleeping.

  • A diet rich in meaty based foods should be provided. Dartfishs color may fade if their diet is not adequate. To entice eating try feeding enriched live Brine, Glass/Grass shrimp, or black worms.

  • Dartfish are shy peaceful fish and should be housed with similar peaceful fish.

  • Dartfish may jump provide an aquarium with a tight fitting lid.
