Finally I found one on Bundlemonster BM-S166.
I stamped this in black over a white base and coloured the stripes with an orange Sharpie.
4 fishy nails would have been too much I think so on the other nails I started with an orange base of Kiko 280, stamped white stripes and then lined them in black Sharpie. I deliberately did the freehand bit wobbly because I knew I wouldn't get it straight but I think it turned out quite well.
Lots of pics, all virtually the same!!!
