How long does it take for fry platy to mature?
20 gallon with red wag platy & other platys. 3 fry looks like two females one male.
It depends on temperature, how much and what food you give them and water parameters. If you have warm water, give them food high in protein and 2 times ( or so) a day and there is no ammonia, nitrites and nitrates and there is lots of space, they will grow like mad, 2-3 months and you're done. If they are the complete opposite it may take over a year for them to mature. Normally, platies are one of the fastest growing livebearers.
I've been having ammonia issues. I switched breeder nets I noticed how dirty it was. Hopefully that will help.
