X12 Dwarf Freshwater Puffer

    Aquarium SetupIn captivity, they are not too picky about water parameters. As long as extremes are avoided, your fish should do just fine. Spawns have been reported by many hobbyists in both hard and soft water with a recorded pH both slightly above and slightly below neutral. I have kept and bred them in water with a neutral to slightly basic pH, a total hardness around 125 ppm (with about half of that coming from carbonates), and a temperature in the mid to upper 70s (F).It does appear that clean water is important. Keep the dissolved organics and nitrates low by doing large regular water changes, especially if you are keeping them in smaller tanks. If you provide them with clean water and the right foods, dwarf puffers will reward you with many years of unique behavior.These fish prefer well-planted tanks with some areas where each male can set up his territory. They do well in smaller tanks, and a pair or trio can be kept in a desktop tank. A good filter helps maintain water
