This video was taken in daylight only, no over head tanks lights. These are some really tricky fish to capture on video. Notice the length of the ventral fins on the two largest ones (females), vs the longer fins on the male who is showing a little bit of colour. Eventually his ventral fins will grow out beyond his tail! The females are not boring either, they can show some amount of blue scales and pearly cheeks, but will never grow their ventral fins past their anal fin.
