Breeding/Reproduction:     Some species of surgeonfish have spawned in public aquariums and there have been a few scattered reports of spawning in home aquariums, but regular spawning and the rearing of the young has not yet been reported.
     Though the Vlamingi Tang has not yet been bred in captivity, the Unicornfish spawn in pairs in the open water. The males can change part of their body into a brilliant color to court a female. A pair will rise to the surface to release their gametes. The eggs are pelagic with an extended larval phase, which probably accounts for the vast distribution of the Unicornfish.
     For more information on breeding and the development of the fry, see: Marine Fish Breeding: Tangs.

-this is exactly whats going on, the color changes are sweosme and its also done near the surface of the tank, in a corner where the waterflow is slow. the rest of the tank has ALOT of flow.

this happens every couple days and is always at the same time. 5-5.5 hours after lights are on.

tell me what you think is happening

Looks like something is going on...

Looks kind of like a dominance display to its reflection in the glass to me. Which--don't get me wrong--is a good sign. Fish that don't have partners don't usually do stuff like that.

ya that was my initial thought but that tank is really bright and i dont think they could see reflections in it and if they could i would still wonder why that behavior is so consistent with time of day. 

Your tank being bright is why they can see their reflections. It's like a house window: During the day when it's bright outside you can see through them, but when it's brighter inside than out they start to get a little reflective. It's worse in tanks because there's more concentrated light.
 
Time of day is just like with most animals: You get up and get to the business of staying alive another day. Eat, work, whatever. Once all those things are done you start getting a little frisky. Displaying for rivals, establishing territory, impressing the mates, etc. Some animals rearrange that and do the frisky thing first. Those tend to be ones--like seahorses--that have social needs that are pretty important and need to be kept constantly reinforced. Well fed animals can get away with being frisky over more of the day.
