Appearance and Sexual Differences
- Short Description: This magnificent fish is easily identified by its elongated, powerful body and the ability to inflate its body when threatened. They often display intricate dark lines or patterns that allow them to change color to blend with the substrate.
- Coloration: Varies widely, usually featuring complex patterns of dark stripes, spots, or bands over a lighter body. Coloration may shift to match the substrate.
- Fins: Short, fleshy fins are typical of puffers. Like all puffers, they have a set of fused teeth that form a powerful beak used for crushing shells.
- Behavior: Highly intelligent, interactive with keepers, and fiercely solitary. They are known to burrow or wallow in sand to hide or sleep and will jump if startled, making a tight-fitting lid mandatory.
Tank Requirements and Water Parameters
- Minimum Tank Size: A minimum of 120 gallons (48″ x 24″ x 24″) is required for a single adult. They are large fish that produce significant waste.
- Schooling: Must be kept alone in a species-only tank. They are notorious for randomly attacking and killing tank mates, sometimes even after months or years of peaceful cohabitation.
- Temperature: Tropical range: 75∘–82∘F (24∘–28∘C).
- pH Level: Highly adaptable, but prefer neutral to slightly alkaline water: 6.5 to 7.5. Pristine water quality is paramount; their waste production necessitates oversized, powerful filtration and large, frequent water changes (50% weekly).
- Aquascape: The substrate must be fine, soft sand (2′′–3′′ deep) to allow for safe burrowing and wallowing. Decorate with smooth rocks, caves, and large driftwood to provide cover and mental stimulation. Heaters must be protected (e.g., placed in a sump or heavily guarded) as they will bite exposed equipment.
Diet and Feeding
The Fahaka Puffer is a specialist molluscivore that requires crunchy, shelled foods for dental health.
- Staple Diet: Hard-shelled foods are essential to wear down their rapidly growing teeth (beak). This includes whole, shelled snails (e.g., Ramshorn, Malaysian Trumpet, Mystery), cockle-in-shell, crabs, and crayfish.
- Supplementation: Offer high-quality meaty frozen foods like shrimp, krill, and white fish. Vary the food presentation (e.g., bury it in the sand) to provide mental enrichment.
- Schedule: Juveniles should be fed daily; large adults only need feeding 2–3 times per week. Overfeeding contributes to poor water quality.
Compatibility
- Caution: They are non-community fish. Never attempt to house two Fahaka Puffers together, and avoid placing any other fish or invertebrate (snails, shrimp) in the tank unless you are prepared for them to be eaten. Use caution when performing tank maintenance, as they can inflict serious bites.
- Good Tank Mates: None. This fish is strictly for a solitary, species-only setup.
