Swelling of the lower leg and ankle is a common problem. Determining the cause of ankle swelling is the first step to finding effective treatment. Once the cause of the ankle swelling is determined, effective treatment can be initiated.
The most common clown fish-and the one that looks most like Nemo-is the percula clown fish which is bright orange with white stripes.
There is a vertical white stripe on the caudal fin. The Clown triggerfish has two dorsal spines, a large one and a small one. The eyes of the fish are set high on its head, and each moves independently so the fish is able to scan its environment completely when looking for food. Males and females look alike.
