Goldenbait /Yamashita uses names like Octopus, Needlefish, Cuttlefish, Kajiki Squid, and Sardine to describe the size and shape.
That one is called an Anchovy. I think they are discontinued, but I bought a 10 pack of solid bright green (A14R) at PNT 2 summers ago. Haven't used them much yet.
I think yours is an A39R, which is a good colour in the other sizes and should work fine, especially if the bait is small.
