Origin
Native to the Western Ghats of Kerala and Karnataka, India—specifically slow-moving, vegetation-rich streams and lakes.

Visual & Functional Appeal
Compact, marble-sized body with shimmering yellow to olive-green hues and black blotches. Constantly active, inquisitive, and expressive. Adds energy and micro-hunting behavior to aquascapes.

Purpose
Useful for controlling small invertebrates like pest snails. Also adds a focal personality to nano aquariums, especially planted or biotope-style setups.

Importance
Unlike most puffers, it thrives in freshwater and stays tiny—ideal for small tanks. Encourages close observation and interaction due to its intelligent and engaging behavior.

Included Resources
Requires a well-planted tank with hiding spots and low current. Sponge or gentle filtration preferred. Parameters: 74–82°F, pH 6.8–7.8. Best in a species-only tank unless experienced with its care.

Best Use Cases
Nano planted tanks (5–20 gallons), Indian stream biotopes, snail control setups. Ideal for intermediate hobbyists wanting a charismatic pet in a small space.

Conservation Context
Endemic to a narrow range and vulnerable to habitat destruction. Overcollection and pollution threaten wild populations. Supporting captive-bred stock is encouraged.

Ideal Aquatic Animals
• Other dwarf puffers (with space)
• Fast-growing plants (Java moss, Anubias nana petite)
• Pest snails (as live food)
• Amano shrimp (risky; only with cover)
• Nerite snails (may be harassed)
