Dwarf Pea Puffer – Carinotetraodon travancoricus: A Comprehensive Care Guide
Introduction:
The Dwarf Pea Puffer (Carinotetraodon travancoricus) is a small, but highly popular pufferfish species that has captured the hearts of many aquarists. Native to the western coast of India, this freshwater species typically reaches a size of 1 inch (2 cm) and is known for its vibrant appearance and lively personality. Its compact size and striking colors make it an excellent choice for smaller aquariums.
1. Natural Habitat and Behavior
The Dwarf Pea Puffer is native to slow-moving streams, rivers, and wetlands in the Kerala and Karnataka regions of India. Preferring soft, acidic water with plenty of plant cover, this species is often found in dense vegetation where it can hunt small invertebrates and crustaceans. Known for being active and inquisitive, it enjoys exploring its environment and is often seen darting between plants and decorations.
2. Aquarium Setup
A minimum tank size of 10 gallons (38 liters) is recommended for a group of Dwarf Pea Puffers, as they are social fish and do best when kept in small groups. They require soft, slightly acidic water, with a pH between 6.5 and 7.5, and a temperature range of 75-80°F (24-27°C). The tank should include dense vegetation, small caves, and smooth rocks for hiding spots. The substrate should be fine sand or soft gravel to prevent injury to their sensitive underbelly.
3. Diet and Feeding
The Dwarf Pea Puffer is a carnivorous species, feeding primarily on live and frozen foods such as bloodworms, brine shrimp, snails, and small crustaceans. Offering small snails is particularly important for keeping their teeth in check, as they can grow too long if not naturally worn down. Feed them small amounts of food 2-3 times a day, as overfeeding can lead to water quality issues.
4. Compatibility with Other Fish
Dwarf Pea Puffers are known to be territorial and aggressive, especially toward other species of pufferfish. They should be kept with similarly sized peaceful species. Avoid aggressive tankmates, as the Dwarf Pea Puffer may become stressed or aggressive itself. They can be kept in small groups (usually 3-6 individuals) to reduce territorial behavior, but it’s best to avoid housing them with fin-nipping or overly active fish.
5. Common Challenges and Tips
- Aggression: Dwarf Pea Puffers can be aggressive toward one another and may become territorial. Provide plenty of plants and hiding spaces to minimize conflicts.
- Tank Size: While small, the Dwarf Pea Puffer is very active and requires ample space for exploration. A minimum of 10 gallons is essential for a small group.
- Feeding: Their carnivorous diet requires a constant supply of live or frozen foods. Snails are especially important for their dental health.
- Water Quality: As with all freshwater fish, keeping the water clean is essential. Perform regular water changes to ensure healthy water conditions.
Conclusion
The Dwarf Pea Puffer (Carinotetraodon travancoricus) is a captivating, small pufferfish that can make a stunning addition to well-maintained freshwater aquariums. Its small size, striking appearance, and active behavior make it an ideal choice for hobbyists who can meet its care requirements. With proper water conditions, diet, and tankmates, the Dwarf Pea Puffer can thrive and bring a lot of joy to your aquarium.
