The ideal aquarium for a Figure 8 Puffer will have brackish water with plenty of hiding places and a sandy bottom composed of an aragonite-based sand. This environment will provide the Puffer with the ideal environment for healthy living and should include both real and plastic plants for it to explore. Care should be taken when housing multiple puffers together, as they might be aggressive to each other. Additionally, the aquarium should be regularly monitored for signs of distress or aggression to ensure your pet stays healthy and happy. Regular water changes and good filtration will also help maintain the aquatic environment.

Spawning in brackish water is a complex process and requires careful observation. The female will lay the eggs on the substrate or on a flat rock, and the male will then fertilize them. The male will then remain behind to guard the eggs for the following 7 days until the fry become waterborne. During this period, it is important to provide the eggs with a suitable environment to ensure successful hatching. Furthermore, the water should be of the correct temperature and salinity in order to ensure the fry’s health and survival. It is essential to ensure that the water is kept clean and free of any contaminants to ensure the fry’s well-being. With the right conditions, the fry can be expected to emerge healthy and strong.

The Figure 8 Puffer is a carnivorous fish that should be fed crustacean foods such as brine shrimp, krill, mollusks, and earthworms. These foods provide the Figure 8 Puffer with the essential ingredients necessary for its healthy development.
