I have seen such a picture of a slender lady "raising fish" at the collarbone, and the fish can swim in a small space. After looking at it, I think slim body is a reason, and more importantly, the fish must be small, so what kind of fish are on the collarbone?
There are many short fish in nature, and most of the fish on the collarbone are juvenile fish that are common ornamental fish, and they are certainly not large. The small size of the fish is concentrated in the "goby fish", they are a large population, known to be more than 800 species, the smallest of which is native to the philippine island of Luzon creeks and lakes, adult males only 0.71-0.97 cm long, weigh only 4-5 mg.
The reason why it is called goby is because it is too small, not like a fish, but like a shrimp, so it is also called gobies.
Such a small fish, whether you are slim or not, it is absolutely no problem to keep a few on the collarbone. The local Filipino women have a special ornament, put the goby in the earrings, and then start the busy day with two fish.
Because of its small size, goby lifespan is not long, and the smaller the life, the shorter it is, generally in two or three years, and the slightly larger one can live to about five years.
Gobies occupied the top spot as the smallest fish for a long time until the end of the last century, when biologists discovered a new species in Australia with shorter body length and lighter weight. Although it has no scales, no fins, and no teeth, it is indeed a fish, and was named "Fat Baby Fish" in 2004.
Its average body length is about 8 mm, its weight is about 1 milligram, I really don't understand where it is fat. Raise it on the collarbone, I guess you can raise a bunch of it.
Unfortunately, this cute little creature has a short lifespan, only about two months, and it feels like it has just come to this world, and it immediately leaves in a hurry. If you are lucky enough to have such a fish, cherish every day with it.
