Extensor Foot Tendons. In the foot diagram below, the main tendons on the top of the foot are labeled. The group of tendons are called the extensor tendons and are responsible for elevating the toes and flexing the ankle up (dorsiflexion).
Dwarf puffers are quite hardy and will tolerate varying water conditions but obviously will do best, as with any fish, in optimum water conditions. They do best at temperatures of 80/26 degrees with a ph of at least 7.
Tropical fish live in temperatures ranging from 75F to 82F hence the need for a good heater to keep the water warm. If kept in less than 5 gal tanks you cannot use heaters, they might heat up the water too fast and cook your fish. Instead, keep your jars in a warm room. Don t be cheap when it comes to heaters.
