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.
It depends on the species, but in general tropical fish are most healthy in the range of 75-80Â°F (24-27Â°C). Cold water fish do better in temperatures well below that, some of them enjoy water well below 70Â°F, which is not suitable for any tropical fish.Ultimately the best temperature will depend on the species of fish in the aquarium.nother time when temperature can have an impact is when a new fish is brought from home and added to an existing tank. Water temperature can change in transit, and again when the fish is added to the new tank. This is an unavoidable issue, but can be minimized by making sure the fish is insulated during transport.
