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.
Perfecting the environment. 1  1. Check the water quality. Guppy fry will grow fast when their water quality is good. 2  2. Keep the water temperature at 75-80F. Do not let the water temperature get outside this range. 3  3. Use a sponge filter or a very low power mechanical filter to keep water clean.
