I wish I had pictures. I had a chocolate mimic tang that I was able to see change from juvi - it found a new home at Ace's school. Also, watched my Xmas grow from about an 1" to 4" before it also found a new home at the Z28's house in Jose's tiny 700 gallon tank. The coloration changes on the wrasse were subtle but, amazing to see. The face showed the color change the most with the body colors becoming brighter.
