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.
If puffers are not offered hard food such as snails and clams, their teeth will grow to the point where they cannot eat anymore. If this happens you have to trim their teeth. To do this, fill two containers with 1 litre of aquarium water each. Add 1 - 2 drops of clove oil to one of the containers.
