According to your tanks listed and the fish you have, The Angel fish are in about a 55 gallon tank. That is about 1/2 the recommended size for that fish. Why would you say a tang needs a thousand gallon tank? Just curious.
Because pretty much all tangs are very active swimmers that also like to sprint for a good stretch once in a while. This you can only give them in a tank with a sufficient surface area and volume.
Large angels and especially regal angels on the other hand are rather calm and need a lot of rock caves and crevices to patrol and hide. You can provide that easily in a smaller tank without them feeling crowded.
Also my regals are still babies with just 3 inch total length and will soon go into my new 100 gallon tank.
