All gar seem to do this in captivity..whats really interesting is they do not do this in the wild. Never could quite figure this out or what this is directly caused by..

Definitely worth looking into further..I naturally work mostly with longnosed rather than some of the other species in-situ so my observations might be biased in just that fishes general behavior...One thing I do know..We will be checking this out in a few weeks
with a different fish.....Found a good night spot!!!I've also witnessed this phenomenon with my gars, they go from very dark (nearly black) to a light bronze/tan shade. Apparently there are two explanations for this when talking about most fish. The most likely reason is that they are missing nutrients in their captive diets that are a common ingredient in the food they ingest or maybe Hormones?
The second, but less likely, cause of color loss may be variations of light. With my gars, they all look lighter after a night in the dark and this shows when I first turn on the lights in the morning. (Spots remain) One gar in particular seems to do this randomly even when the lights are constant. So it may also be a behavioral (camouflage) trait.
Many fish change coloration in response to their natural surroundings. Shrimp gobies that live on black sand bottoms are more colorful than the same species living on lighter substrate. And gobies from turbid mangrove areas are usually brighter than ones from clear habitats.
