You guys are looking at this as science project it’s not at all, the fish will spawn and the fry will grow out sure there are some basic properties, but nowhere near
What you trying to do, I have a 3 year old pair of blues that just got it right, and a 1 year old par that has it downs my P.H is 7.8 and 300-400 TDS I turned the big filter
Off, using a sponge filter now, so the fry grow out and not get sucked up lol going on my rant, it’s been 9 days and there growing fast after about 17-21 days
I’ll blend my own food and they will be just fine, I’ll up load a few pic's for yea these fish have been bread so many times with so many different strands
There no more difficult then raising a gold fish.
