Dwarf pea pufferfish are carnivorous and despite their cute appearance, they have quite a fierce appetite! In the wild, these fish mostly ear small insects, larvae, and algae.
In captivity, you’ll need to give them protein-rich food with a good mix of variety.
Frozen and live foods such as bloodworms, brine shrimp, tubifex, and mosquito larvae are perfect. These will give them the nutrients and protein they need, and serve as a great source of enrichment as well.
It’s important to make sure you’re not overfeeding them for the sake of their health. Due to their appetite, it’s quite easy to give these fish too much food. Aim for a two a day feeding schedule.
Another reason why it’s bad to overfeed your pea puffer is the effect the extra food can have on water quality. Uneaten food will settle in the tank and begin to break down. This process will slowly compromise the water in your tank and cause a rise in nitrate and other substances.
