So I cleaned my 6 gallon out earlier and my male guppies seemed to enjoy the sun, so I put them in a large jar, holds about 1 gallon, for about 15 minutes out in the hot sun and the they loved it! Their colours shone and they were swimming about happily!
Here are some pictures, the first of of them during normal light and the other 2 are of out in the sun.
Normal Light.
In the Sunlight.
