Origin

Carinotetraodon salivator, commonly known as the Striped Red-Eye Puffer, is native to Southeast Asia. Its natural distribution includes slow-moving freshwater streams and peat swamp forests of Malaysia and Borneo. These habitats are typically soft, slightly acidic, and rich in leaf litter and submerged vegetation.

Short description

This small freshwater pufferfish grows up to 5 cm (1.97 inches) and is known for its striking red eyes and striped or mottled body. While they are peaceful toward their own kind, they tend to be aggressive and territorial toward other species. Due to their sensitivity and waste production, it's best to house them in a species-only setup with ample filtration. Each fish should have at least 10 gallons (38 liters) of space.

Tank requirements

A well-cycled aquarium of at least 40 liters (10 gallons) per fish is necessary. Use a soft, sandy substrate with plenty of live or artificial plants, driftwood, and hiding spots to reduce stress and encourage natural behaviors. Dim lighting is recommended to mimic their native habitat. Keep water parameters stable, with a temperature between 22–26°C (71.6–78.8°F), pH of 6.6–7.6, and dGH between 5–20 °N.

Tank mates

Despite their small size, Striped Red-Eye Puffers are aggressive toward most other species and should be kept alone or in a carefully managed species group. Never house them with slow or long-finned fish. If housed in a group, provide plenty of hiding spots to reduce territorial disputes.

Behaviour

These puffers are semi-nocturnal, often more active in the early morning and evening hours. Once they become accustomed to their keeper, they may shift their routine and actively greet you during feeding time. They are intelligent and inquisitive, often inspecting their surroundings and showing individual personalities.

Diet

Carinotetraodon salivator is a carnivorous species and should be fed a varied meaty diet. Offer frozen bloodworms, krill, mosquito larvae, and snails. Occasional live foods help stimulate hunting behavior. While their teeth don’t grow as rapidly as other puffers, shelled foods still help prevent dental issues.

Sexing

Males are more colorful and slightly larger than females. Females typically have a more subdued, mottled brown pattern with a paler underside, while males exhibit stronger stripe contrast and redder eyes.

Breeding

In captivity, breeding is possible but requires patience. The male initiates courtship through displays and circling the female for several days. Spawning occurs on flat surfaces or the substrate. Post-spawning, the male drives the female away and guards the eggs, which hatch in about 3 days. Fry become free-swimming a few days later and should be fed Infusoria followed by newly hatched brine shrimp.

Lifespan

Although their exact lifespan in captivity is not well-documented, it's believed they can live up to 5–7 years under optimal conditions with proper care.
