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.
The Porcupine Puffer is also known as the Porcupinefish or Porcupine Pufferfish. It has spiny appendages which cover most of its body, which may vary from light gray to mottled tans, sometimes with dark spots. Its teeth are actually a fused beak-like structure. 180 gallon or larger, fish-only aquarium with a good protein skimmer is a suitable home. It may be aggressive at times, nipping the fins of tank mates and leaving a circular hole as its mark. It will eat invertebrates found in a reef aquarium.
