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.
Puffers vary in size  the smaller species only growing to 3 inches and the largest reaching over 2 feet in length. Puffers are generally hardy and do best in large tanks with lots of swimming space and some rocky decor dÃ©cor for. shelteruffers are comical looking fish, especially when they are puffed up and look like a ball with fins. By rapidly swallowing water or air, they are able to expand their bodies up to 2 times their normal size in order to deter predators.
