This fishy is a pastel blue called periwinkle with daffodil and carrot stripes. Unfortunately this blue is very hard to photograph to get a true colour– the blue of the pectoral or fore-fin is the most accurate. The fish only has a pectoral fin  on one side as I find a finless side sits better against the neck in a necklace. Please feel free to request fully finned fish for my next showcase if you would prefer.
27mm mouth to tail fin, 17mm dorsal fin to belly
