Your albino Oscar's fins should not be turning black under normal circumstances. They can be turning black due to conditions such as too much ammonia in the water. Get your water tested to make sure.
No not really. It sounds beautiful though.Their are longfin Oscars and are normally more expensive.
Its normal just rare. You can sometimes buy Long-finned Oscars from pet stores but its hard to find.
You might be able to get away with it, but honestly i don't think it's a very good idea. The Oscars are likely to nip the fins of the koi. Oscars are much more aggressive

Cooling fins on a refrigerator are typically thin, metallic and silver or gray in color.
No. Albinism is an inherited condition present at birth, characterized by a lack of pigment that normally gives color to the skin, fins, hair, and eyes. Many types of albinism exist, all of which involve lack of pigment in varying degrees.
Original answer - "i don't know but try this. put a dead fighting fish in a tank that has albino tiger barbs OR tiger barbs and see if the fish attack or eat the dead fish."I have an albino tiger barb, and through my research and experience I can almost guarantee that a fighting fish and an albino tiger barb will absolutely not do. Scientists don't know why tiger barbs have an unusual fin nipping behavior. I emphasize this especially if the fighting fish is the Siamese kind. Long fins+tiger barbs=bad choice. My albino even nipped the other albinos' fins, which proved fatal. Don't take your chances.Sources - "Aquarium and Pondfish", personal experience.
The cooling fins of a refrigerator are painted black to improve heat transfer efficiency. Black color absorbs more heat than lighter colors, helping the fins dissipate heat more effectively. This process enhances the overall cooling performance of the refrigerator.
Oscars are carnivorous and have large appetites. They should be fed a variety of foods such as high-quality pellets, live or frozen foods like bloodworms, brine shrimp, and feeder fish. It is important not to overfeed Oscars as they can easily become overweight.
