Is Bichir Senegal Right for Your Tank?

Bichir Senegal is a moderate-care fish rated "advanced" (3/5). Suitable for hobbyists with some experience who can maintain stable water parameters. They need at least 75 gallons — a mid-size tank commitment. Plan your space accordingly.

Bichir Senegal is semi-aggressive — they can live with others but may bully smaller or slower fish. Choose tank mates carefully. They are territorial — provide adequate hiding spots and maintain enough space to reduce aggression. Expected lifespan: 15 years with proper care.

Common Mistakes with Bichir Senegal

Relying on a heater without a thermometer

Bichir Senegal needs 7582°F. Heaters malfunction or drift over time — always use a separate thermometer to verify. Temperature swings of even 3–4°F can trigger stress and disease, particularly ich.

Putting them in a tank under 75 gallons

Many beginners underestimate tank size needs. Bichir Senegal requires at least 75 gallons — ideally 113. Cramped tanks lead to stunted growth, aggression, and poor water quality.

Housing with peaceful nano fish

Bichir Senegal is semi-aggressive and territorial — small, peaceful species like neon tetras, endlers, or celestial pearl danios will be stressed, bullied, or eaten. Choose tank mates that can hold their own.
