I have VT I bought because it had a purple body. I love purple! Unfortunately, I rarely get to see the purple unless Chablis feels as if it's a purple day. She might purple for a minute or so at feeding time. Chablis goes from purple ,red to yellow. Mostly Chablis chooses a brown body color with red accents on the head and fins. One morining I awoke to Chablis as a brown fish with mustard gas yellow fins and hour later they were orange. Today she is brown with red fins and a red head.
I might add some of the fish that will soon be Chablis' tank companions have red or brown in their bodies. They are in sight of each other. Does anyone else have fish that changes colors often? I think I am going to have to start photographing her changes.
