Keeping your Electric Blue Jack Dempseys thriving requires paying close attention to their habitat setup and care routine:

  • 25-30% weekly water changes

Substrate and Decor

  • Fine gravel or sand substrate
  • Driftwood, rocks, cave structures for hiding
  • Hardy plants like Java Fern and Anubias
