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.
A fish can have up to three dorsal fins. The dorsal fins serve to protect the fish against rolling, and assist it in sudden turns and stops. 1  In anglerfish, the anterior of the dorsal fin is modified into an illicium and esca, a biological equivalent to a fishing rod and lure.he pelvic fin assists the fish in going up or down through the water, turning sharply, and stopping quickly. 1  In gobies, the pelvic fins are often fused into a single sucker disk. 2  Pelvic fins can take many positions along the ventral surface of the fish.
