Hi folks....
Back... WAYYY Back when I was raising fish as a young kid WAY BACCKK in the good olden days... in the mid 60's and beyond, I was told time and time again by various people that good water changes were essential for fry to grow.
There was a little old lady up in Eureka Montana at the time that had the hugest swordtails I had ever seen at that time and since then. She had green, red swordtails that were in the 4 inch range easily.. Platies that were almost as huge.. Her secret... Changed water every two days.. She had a well so that was easier to do...
Then there is a fellow up North in Cleveland, Ohio by the name of Frank Mueller who has an automated drip system that changes his water by 10 percent each day. His fronts were 16 plus inches inside of a year and half... just huge...
I read a lot of articles back in those days from the TFH, Axlerod and others and I remember reading articles that pertained to fish excreting a thyroid growth inhibitor that affected the other fish or similar sized fish.
If fish A was two inch... the excretion was such that it limited all the fish below two inches from catching up and passing fish A.. and so forth.
Maybe I am not googling this right, but am trying to find out more about this...
In addition to the limiter of growth, we know the water quality is so very important as to the other parameters such as excretion of waste, the enclosed system, unnatural food and unnatural way of eating the food. So with that in mind.
Are there any of you folks that have done any kind of comparison with others and noticed either excellent growth or lousy growth of your fry...
Just wondering
Bill

It could be that they are just fat, so they look larger than average.
