I wonder if what we call "Runt of the litter" is actually a form of dwarfism?
Dwarfism in fish?

There isn’t dwarfism in my car, even though he is the “runt of the litter”. He is 17 pounds, and not fat. Just huge, lol

I’m late however I’d like to reply still.
I do firmly believe that it is possible, my main evidence is the existence of dwarf coral platties. They breed true from what I understand, if a thousand different fish keepers all have the same experience with them staying far smaller than normal platties then I am forced to come to the conclusion that it is not simple luck that it happened.

Any idea on the size of the catch location? Ik if it's a small body of water it might be along the same lines as island dwarfism, where the animal just continues to get smaller over the generations just due to environmental pressures. Granted the reverse is also possible, where if there is no natural predators, the animal may increase in size just due to the lack of certain environmental pressures.
Ik at one point both of those happened on the same island at the same time. There was a group of mammoths that got land locked on a tiny island along with a specie of swan and well the mammoths grew smaller and smaller over the generations untill they were roughly the size of a large dog while the swans on the other hand, due to there being no natural predators at the time, started to get extremely big and eventually got as tall as 4.5-5 ft tall and weighed over 100lb. Lol the swans literally got so big and fat that they could no longer fly anymore. All of these animals went the way of the dodo once early man set foot on the island.
But honestly tho it's really neat and interesting to see that some really crazy stuff can happen just from being isolated from your own kind.
I believe, don’t quote me, it wasn’t a catch location, just someone found some that stayed smaller and kept breeding them. I could be wrong though, my memory is hazy on it.
It's definitely possible. Probably ended up with a few small guys and just kept breeding em for the smaller body till it became a permanent trait. Either that or something about their natural environment was causing them to become smaller and smaller, probably a newer adaptation that made living easier for them in some aspect. Kind of like how black panthers are slowly but surely starting to replace the regular colored Jaguar just due to a random mutation that made their lives easier for em.
Most fish, especially alpha males gives give off growth inhibiting hormones.
In most case in nature they are of little consequence because of the large volumes of water.
But in the confines of a closed system like a tank, these hormones can build up, to the point they even affect the fish giving them off, most tanks are in comparison small.
But even in large tanks, they may hinder growth, especially if the tank is overcrowded, or water quality management is lax.
Along with the growth hindering effects of nitrate buildup, the only way to get rid of these substances, is with frequent large water changes, or rather advanced filtration like fractionation.
