Glass Knifefish Aquarium Care Guide

Keeping Glass Knifefish in an aquarium requires the right conditions.

Aquarium Information

• Care level: intermediate
• Temperament: peaceful
• Diet: carnivore
• Minimum tank size: 50 gallons
• Compatibility: Generally peaceful with other non-aggressive, similarly sized fish. Avoid fin-nippers or overly boisterous tankmates. Can be kept in groups if the tank is large enough and provides ample hiding spots, though males can be territorial towards each other.
• Special requirements: Requires a well-filtered aquarium with subdued lighting, plenty of hiding places (driftwood, PVC pipes, dense planting), and a soft substrate. Sensitive to water quality, so regular water changes are crucial. They are nocturnal and will be more active after lights out. Due to their electric organ discharge, avoid placing sensitive electronic equipment too close to the tank, though this is generally not an issue for typical home aquariums.
