By wild spots i mean the spotting in the fins of the fish you see that are hybrids of smaragdina etc. Small horizontal black markings or dots or web like spots. They are indicative of a hybrid , like stripes in a savannah cat or rib bars in a bengal or solid markings of a zorse or the cow shape of a beefalo
Fish anatomy is the same regardless of size if someone wanted to milk them they could manage it if only by cutting the fish open and taking what they want, not beyond the scope of the kitchen table - the little things might not survive but I bet I could get the eggs out of a laden hen betta, milt might be more difficult but the larger species male would make it easier than a splendens. Not saying that's what happened just saying More things are possible than some might think worth while and a lab can be categorized in many varied ways. I've seen enough to know a lab is just a room where "science" happens.
Asians have accomplished many difficult and tedious tasks with regards to fish keeping and often in "labs"What's worth it to one man is worthless to another. if I had the money it would be worth creating gametes from germ cells of my neutered male dog in a Korean lab to produce young with my intact female dog. Sooo worth it, but no one else except the people that know them, would think so.
two rich old asians walk int a betta ring and start bragging about how big theirs is, one takes out his giant and all the others are duly impressed, IT WAS WORTH IT.lol
