This is my first time with splitfins/goodeids. I bought (5) fry in august last year. They’re currently about 2 inches long and roughly 6-7 months old. So far they all look female still and obviously I was hoping for at least one male. I was wondering if someone more experienced could give me an estimate on when they start to sex out.
Tank stays about 68-70 degrees Fahrenheit in the winter.
