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.
For typical freshwater fish, the temp in my aquariums is between 70 and 78 F. There are others that require higher or lower temps, for instance blind cave fish can take 63-75 F, and Bettas as high as 70-85 F. Saltwater aquarium fish typically come from the tropics, so 75-80 F is best.eport Abuse. Tropical temperature range is considered to be 72-84Âº F/22-29Âº C Below this range for room temperature (coldwater) aquariums. Time light is left on would largely depend on the plants, if any, you're keeping with the fish. Generally, no more than 8 hours.
