Colomesus tocantinensis

Colomesus tocantinensis, commonly known as the Tocantins Puffer, is a medium-sized pufferfish species found in the freshwater systems of Brazil. Known for its unique body shape and vibrant coloration, this pufferfish tends to be more peaceful compared to other puffer species. ### Care and Maintenance: - **Diet**: Primarily carnivorous. Feeds on mollusks, crustaceans, and insects. Ensure a varied diet to meet their nutritional needs. - **Behavior**: Somewhat shy and peaceful; can be kept with other non-aggressive species. - **Habitat**: Requires a well-structured tank with ample hiding places such as rocks, caves, and plants. - **Health**: Sensitive to poor water quality; regular water changes and filtration are necessary. - **Compatibility**: Best kept in a species-only tank or with other small, non-aggressive fish. Avoid fin-nippers or overly aggressive species. ### Breeding: Information is limited, but breeding them in captivity has proven challenging. They are not known to be prolific breeders in aquarium settings. **Special Remarks:** Care should be taken to ensure they are not housed with invertebrates due to their natural inclination to nibble.
