Pea Pufferfish (also called dwarf puffer or Malabar/pygmy puffer) are tiny, round freshwater fish with bright spots and big, curious eyes. They’re one of the smallest puffer species (about the size of a pea!), loved by hobbyists for their bold personalities and playful swims. Despite their small size, they are active, smart, and need special care compared with many common tropical fish.

Origin

  1. Pea puffers come from the slow, heavily planted rivers and streams of the Western Ghats in southwest India (Kerala and southern Karnataka). In the wild, they live among dense plants and breed in small groups.

Pea Pufferfish Temperament

  1. Mostly bold, curious, and very interactive with keepers.
  2. Can be territorial and sometimes nip at or bully other fish — especially other pea puffers if the tank is too small.
  3. They are not schooling fish; they like to explore, chase snails, and guard small territories.

Compatibility

  1. Best kept either alone or with very carefully chosen tankmates. Good options: very fast, robust mid-to-top swimmers that won’t be bothered by a puffer (but even these aren’t ideal).
  2. Avoid slow, long-finned, or shy fish (they may be nipped), and avoid shrimp or most small invertebrates because pea puffers like snails and small critters.

Pea Pufferfish Price range

  1. In India, the price of a Pea Pufferfish / Dwarf Pufferfish usually falls in the range of ₹300 to ₹800 per fish (small/juvenile, captive-bred), depending on city, availability, and health.

Pea Pufferfish Habitat Requirements

Initial Setup Cost

₹3,000 - ₹6,000

Water Temperature

24º -28ºC

Water Type

Fresh Water

PH Level

6.5 - 7.5

Tank type

  1. Freshwater only. They prefer calm, planted tanks with lots of hiding spots.

Pea Pufferfish Aquarium size

  1. Single puffer: minimum 5–10 gallons (20–40 L).
  2. Small group (very carefully managed): 10+ gallons (40+ L) and lots of space and plants. Bigger is always safer to reduce aggression.

Water conditions

  1. Temperature: about 24–28°C (75–82°F).
  2. pH: roughly 7.2–8.5 (stable is more important than exact number).
  3. Hardness: 5 and 20° dGH, low to moderate; keep parameters steady and test regularly.

Environment needs

  1. Dense live plants, lots of floating cover, caves, and smooth rocks. These give hiding spots and break lines of sight to reduce fights.
  2. Gentle filtration (sponge filters are great) — puffers dislike strong currents.
  3. Substrates can be fine gravel or sand. Avoid sharp decorations because puffer skin and barbels are delicate.

Pea Pufferfish Nutritional Guide

Avg Monthly Expenses

₹50 - ₹ 100

Diet type

  1. Primarily carnivores, they need protein-rich foods and often prefer live or frozen foods.

Pea Pufferfish Suitable foods

  1. Best: live/frozen small snails, bloodworms, daphnia, brine shrimp. Snails help file down their ever-growing teeth (beak).
  2. Some will accept frozen or prepared meaty foods, but many pea puffers refuse flake or pellet-only diets. Offering snail meat or whole small snails helps dental health.

Feeding Frequency & Tips

  1. Feed small amounts 1–2 times daily. Remove uneaten food quickly to keep water clean.
  2. Rotate foods so they get varied nutrition. Offer snails regularly (or snail meat) so their teeth don’t overgrow. If teeth overgrow, they may need veterinary care or special feeding to wear teeth down.

Some of the common health issues found in Pea Pufferfish (Carinotetraodon travancoricus) are as follows:

Overgrown Teeth (Beak Issues):

Pea puffers have teeth that constantly grow. Their teeth might grow too long if they do not eat enough snails or similar foods. Due to this, eating becomes difficult for them. Their teeth are kept filed down via regularly offering shell-based food or snails.

Fungal and Bacterial Infections:

Poor water conditions or stress can lead to problems like fin rot, cloudy eyes, or body fungus. Symptoms may include faded colors, clamped fins, and refusal to eat. Treatment usually involves improving water quality and using appropriate fish-safe medications.

Parasitic Infestations:

New or stressed pea puffers may develop parasites like Ich (white spot disease). Signs include scratching against tank objects or white cysts on their body. Treatment requires anti-parasitic medication and keeping water parameters stable.

Preventive Care:

Before you are introducing them to the main aquarium, you must always quarantine new fish for about 2 or 3 weeks. Clean water and stable parameters must be maintained, and a balanced diet must be offered. For preventing diseases, it depends a lot on these actions.

Pea Pufferfish General Health Tips

  1. Test water regularly: ammonia and nitrite should always be 0, nitrates should be kept low.
  2. Use a gentle filter with low current to avoid stressing them.
  3. Reduce aggression and stress by keeping plenty of plants and hiding spaces.
  4. A varied, protein-rich diet helps improve immunity and overall health.
  5. Carry out regular partial water changes to maintain a stable, clean environment.
