Chelonodon patoca - Milk Spotted Puffer | Indian Native Series

Chelonodon patoca, commonly known as the Milk Spotted Puffer or Brackish Puffer, is a fascinating species native to the brackish and coastal waters of South and Southeast Asia. Known for its striking patterns and inquisitive nature, this puffer is highly sought after by aquarists specializing in brackish or marine tanks.

• Geographic Spread: Found in estuaries, mangroves, and brackish water habitats across the coastal regions of India, Sri Lanka, and Southeast Asia. Its range extends from the Arabian Sea to the Indo-Pacific region.
• Water Conditions:
  • Temperature: 24–28°C
  • pH: 7.5–8.5
  • Hardness: Medium to hard
  • Salinity: Prefers brackish water but can adapt to full marine conditions.
• Care Needs:
  • Requires a spacious tank with brackish water conditions and hiding spots created with rocks or driftwood.
  • Omnivorous diet, feeding on mollusks, crustaceans, and live or frozen food. Hard-shelled prey like snails are essential to maintain dental health.
  • Semi-aggressive; best kept alone or with large, robust tankmates in a species-specific or brackish community setup.
  • Sensitive to poor water quality; requires strong filtration and frequent water changes.
• Additional Notes:
  • Grows up to 17–18 cm in captivity, with larger specimens seen in the wild.
  • Known for its ability to inflate when threatened, a defense mechanism common to pufferfish.
  • Displays unique milk-like patterns on its body, giving it its common name.
  • As with all puffers, it should not be kept in a planted tank as it may damage vegetation while foraging.

Chelonodon patoca is a species that captivates aquarists with its personality and unique care requirements. While it requires specialized conditions, its striking appearance and engaging behavior make it a rewarding addition to well-maintained brackish or marine aquariums.
