These tiny, personality-packed fish, also known as Carinotetraodon travancoricus, captivate with their curious nature and unique looks. Originating from the freshwater rivers of India, pea puffers have soared in popularity among aquarists.

Their care involves maintaining a tank with parameters that mimic their natural habitat, which includes warm, slightly acidic water and a densely planted environment. Diet-wise, they prefer live foods but can adapt to frozen or dried alternatives that are rich in nutrients.

Pea Puffer Care

Let’s explore how to set up the perfect home and maintain ideal water conditions for your Pea Puffers.

Tank Setup

Setting up the right environment is crucial for Pea Puffers. They need a tank that mimics their natural habitat. Here are the essential steps:

  • Size: Start with a minimum 10-gallon tank for one Pea Puffer. Add 5 gallons for each additional puffer.
  • Plants: Include live plants like Java Fern and Anubias. These plants provide hiding spots and mimic their natural environment.
  • Substrate: Use fine sand or smooth gravel. This protects the delicate bellies of Pea Puffers as they explore.
  • Decoration: Add caves and driftwood. These features offer additional hideouts and enrich the tank’s layout.
  • Filtration: Install a gentle filter. Strong currents can stress these small fish.

Water Parameters

Maintaining the right water parameters is vital for the health of Pea Puffers. Here’s what you need to know:

ParameterIdeal Range
