I have been using this for about a week now and I am actually noticing a
marked difference in the color of my Piranhas. I have never used processed
food before and now I am feeding this to the fish every-other-day. They now
show a distinct color on each part of the body. Black on the head and
surrounding areas (on the top running to just to the end of the head area).
Dark blue from the black area on the head to the start of the tail. Blood
red starting at the lower jaw, and continuing along the sides and undersides
to the long red lower fin that extends to near where the tail starts. At
the tail just where it starts to leave the main body is a black stripe,
followed by a white stripe, and another black stripe at the very end of the
tail where it fans out. Needless to say I am quite impressed with this food
supplement and now know first hand that when they say "contains color
enhancing vitamins" on the label they damn well mean it

Beta carotine is what does it. You can get the same results (cheaper)
by raising crickets and gut loading them with grated carrot.

Paprika does it too. Get carrots or paprika in your fish *somehow*
and they'll color up. The reds are mostly affected. Paprika also
turns (red factor) canaries red.
