Red bellied piranhas?

I'm not sure where this should go but i guess ill put it here :D
I was wondering if you have them, does their usual red bellys turn white at night for some reason?
During the day their stomachs are BEAUTIFUL as in VERY VERY red and pretty then it seems like as soon as it goes dark (with no light on) their stomachs go mostly white, does this happen because their sleeping or something? They act normal, don't show any signs of anything wrong at night.
Theres 4 of them in a 55 gallon and they all get along fine. I know theres suppose to be more than 4 but I had 6 and couldn't keep the tank clean so I found 2 of them a home with a big group in a custom 200 gallon (lucky 2 eh?).
Tanks around 77-80F all day. I would like to get a pic of them but these guys dart when I put the camera up to the tank lol I think I may need something better than my digital camera for these guys lol
I'm just curious if anybody else who has them notices this :D
Anybody got any idea's?

It could be the color of the light. I have heard of color-enhancing lights.

Yeah but the thing is the light isn't on at all during the day, and their bright red, just with sunlight in the room. Then when I get home from whatever its dark, and Ill turn on the room lights then the tank light and their all white =X! I think it may be just because its dark, I've had the light on for about a half hour and their starting to get their color back =D! Maybe when their inactive they turn white?? hmm

Fish change their colors according to their mood and when inactive. Your thread has been moved in Characins section.

I know there are other charcins that become much duller when it's dark. Neons, and black neons for two. There are some pencilfish that change from striped to mottled at night. Don't see any reason why it wouldn't be the same for piranha.

my red bellies do not turn colors, and i am unsure why yours does. I do know what your talking about with the nice rich colors, the colors and the silver shine.
