18 inches and 300 grams is the accepted size for breedable females though you want to make sure that their age is compatable with breeding as the chances of egg binding and infertile clutches in younger females is much higher than in appropriately aged ones. I took in a 12 month old female that was adult size and was bred. She laid 1 clutch and of that clutch only 1 egg was fertile. This was due to her being to young to successfully breed. No reason to breed them so early you can breed a female up to her 6th or 7th year.
I just set Swordtail's timer for his bath and paused it so I could actually fill his soaking bowl up and he crawled over my phone and canceled the timer
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
