Overview

Dwarf Pufferfish (Carinotetraodon travancoricus) is a middle swimmer for aquariums where the layout leaves enough open swimming space and the water stays stable.

Use these values as planning checks, then make sure the aquarium still has room for behavior, group needs, and calm community fish.

Care requirements

With a Intermediate care level, Dwarf Pufferfish is best for aquarists who can keep water quality steady and plan compatibility before adding the fish.

Because it uses the middle part of the aquarium, leave enough open swimming space instead of crowding that part of the aquarium.

Plan the aquarium around the group, not just one individual.

With a lifespan of up to 5 years, this is a fish to plan for long term rather than an impulse addition.

Aquarium size and space needs

An aquarium of 120 L or larger can be a reasonable starting point, but it should not be read as permission to overstock.

At up to 3.5 cm, Dwarf Pufferfish stays small, but a group still needs room to move, feed, and avoid constant competition.

Uses the middle part of the aquarium, so leave enough open swimming space for movement and feeding.

A group of 5 or more should have enough open swimming space for movement and feeding.

Water parameters

The temperature range for this fish is 22 to 27 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.

The pH range for this fish is 6.5 to 7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.

The GH range for this fish is 5 to 25 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

The KH range is 4 to 10 dKH. Use it as a general stability reference rather than a reason for aggressive adjustments.

Temperament and compatibility

Dwarf Pufferfish should be planned cautiously with compatible fish only, because aggressive temperament data raises the risk of conflict.

If kept in a group of 5 or more, the aquarium should have enough open swimming space for the group rather than being planned around a single fish.

Because this fish uses the middle part of the aquarium, compatibility is easier when other fish are not all competing for the same swimming space.

Swimming zone and behavior

This fish uses the middle part of the aquarium, so leave enough open swimming space for movement and feeding.

Because this species is best planned as a group of 5 or more, plan the aquarium around the group rather than a single fish.

Feeding

As an omnivore, Dwarf Pufferfish should receive a varied diet rather than one repeated food type.

Natural habitat and origin

This profile currently lists the origin as India. Treat this as a broad regional note rather than a complete habitat description.
