Sapphire Toothcarp

Sapphire Toothcarp (Priapella chamulae)

A rare and elegant livebearing fish from the fast-flowing, clear streams of the upper Río Grijalva system in Tabasco, Mexico. Described in 2006 and named after the indigenous Chamula people of the region, this species stands out for its refined appearance and specific habitat requirements. It is one of the larger members of the Priapella genus and remains little-known in the aquarium hobby, making it a true collector’s item for enthusiasts of rare livebearers and Mexican biotopes.

Key Features

• Maximum Size: 4.8 cm / ~1.9 inches SL.
• Appearance: Slender, streamlined body typical of stream-dwelling livebearers. The “sapphire” name hints at its subtle iridescent qualities, though specific wild coloration is understated with a focus on form and movement. Males possess a specialized gonopodium for livebearing.
• Fin Details: Dorsal soft rays 9–10; anal soft rays 10. Males have a distinctive gonopodium with membranous hooks and processes.

Aquarium Care

• Tank Size: Minimum 20–30 gallons for a small group (long tank preferred to allow swimming space).
• Water Parameters: Tropical to subtropical freshwater with current; 75–82°F (24–28°C), pH ~8.0, moderate hardness (10–15°dGH). Excellent water quality, high oxygen, and moderate to strong flow are essential. Use sand or fine gravel substrate, minimal vegetation, and plenty of shade from driftwood or overhanging plants.
• Diet: Omnivorous — accepts high-quality flakes, micro-pellets, and small live or frozen foods (brine shrimp, daphnia, bloodworm).
• Behavior: Peaceful, active swimmer that appreciates current. Best kept in groups with other small, non-aggressive fish from similar habitats. Livebearing; females give birth to relatively few but well-developed young. Sensitive to poor water quality and temperature fluctuations.
