Valentini Puffers are relatively hardy when kept in stable and well-maintained conditions, but like all marine fish, they are susceptible to certain diseases, particularly when stressed. One of the most common issues is marine ich, which appears as tiny white spots on the body and fins. They may also suffer from internal parasites or bacterial infections, especially if they have been imported recently or housed in overcrowded conditions. Early signs of illness include scratching against rocks, rapid breathing, a loss of appetite, dull coloration, or visible wounds. Because puffers are sensitive to copper-based treatments, it’s usually safer to treat them in a separate quarantine tank using less harsh methods such as raised temperatures and specialised reef-safe medications. Preventative care is always better than reactive treatment, so maintain a regular cleaning schedule, perform partial water changes weekly or fortnightly, and monitor your water parameters closely. By keeping stress to a minimum and feeding a nutritious diet, your Valentini Puffer will enjoy a long and healthy life in your marine system.

Caring for a Valentini puffer fish takes some effort, but the payoff is immense. With the right tank setup, a tasty and varied diet, and a bit of TLC, you’ll have a dazzling centrepiece for your aquarium. Got any questions or your own puffer tales?
