There are tails and then there are tails.
In general, a "Veiltail" is a breed of fish - that carries a very long tail that is "flat" on the back - with no forking. Picture a triangle - the top point of the triangle is attached to the fish's body and the flat base of the triangle is the back of the tail - flat. A true veiltail will "droop" - actually that may be a misleading word for thetail should not look droopy, but drops down behindthe fish like a long train or veil is carried behind.
A different breed of fish can carry a veiltail, though. This means that it will have a long, flowing tail that has the flat back to it and it will drop in a train or veil behind the fish.
A fish that has a very long tail with the flat back shape, but the tail is held up in a standard angle for the fish is called a broadtail on the fish. (My avatar is a Ryukin with a broadtail)
Yet another modification in comportment of the flatbacked tail is the open tail that a Tosakin carries - a well bred Tosakin will have that tail opened out rather in a flat presentation - with the edges curled up and over to create the distinctive Tosakin look.
Your Oranda appears to have a slightly larger than normal tail for an Oranda - and it does appear to have the flat back to it. I think I would classify him as a broadtailed Oranda. A very pretty fish, that!
