Attendant phobias may merge to create this condition of aviophobia. For example, acrophobia (a fear of heights) may merge with claustrophobia (a fear of being in a small enclosed area) to form an extreme fear of being trapped in the confines of the seating area of a plane and not being able to leave the space because the plane is in flight.
Most aquarium fish can regrow their tails to some degree. However, this ability is not magic. You need to identify the cause of the fin damage and correct it to prevent recurrence.You will also need to provide optimal conditions to encourage regrowth.sually, a fish will regrow fins without incident. But sometimes, fin rot and other disease may impair its ability to do so. If you see signs of infection and salt doesn't help, consider purchasing antibiotics from the pet shop.
In some fish, e.g., the eel, a single fin extends from the back, around the tail, and along the ventral surface. In the majority of fishes, however, there are one, two, or three dorsal fins, a distinct tail fin, and an anal fin. These are called median, or unpaired, fins.In addition to these unpaired fins, most fish also have paired fins.he tail is an important organ of locomotion and the paired fins are used for steering, checking speed, balancing, and for slow movements. An adipose fin (fatty tissue without support) is found behind the dorsal fin in some fish, e.g., the salmon and the catfish. See climbing perch; flying fish. Cite this article.
