2 Redeared Sliders

I was given 2 RES’s about 3 months ago. They’re eating well, growing like crazy and appear to be happy in their temporary home. I’m working on a 150gl pond set up for them by winter time. I guess my main question is how to tell if I have males or females? They’re about 2 inches now so I’m not even sure of their age or how to tell. Thanks for any ideas

When they are mature, the males have long front claws. Much much longer than on the rear feet. The females front claws are approximately the same length as the rear feet.

Male tails are also wider and thicker. But the feet is the dead giveaway. Females also, when adults, are much larger in size. You can't really tell sex on hatchings that I am aware of.

I agree with tansy. With RES's that will be reached when they are about 4" in shell size to tell for sure. Small babies and juveniles are even hard for a trained Herp Vet to tell.

If it turns out to be two male's the day will come that aggression starts and will need to be separated. Even a 150 gallon full of water will not be enough territory for two males once sexually mature. Some are lucky that takes years but that day will come. Two female would get along better and that depends if there personality's are about the same. If male and female the male when sexually mature will just harass the female for sex until she really hurts him or worst.

Adult males can get around 9" and adult females 12" needing 10 gallons for every in of shell. Yes some get lucky depending on there DNA and do not grow to there full potential requiring a smaller tank but... Large glass tank's gets costly or go to stock tanks which saves a lot of money. If you stay in this hobby over 50 years as I you will find RES's get larger than one thinks. Something to keep in your thoughts before you setup there final home or go with several upgrades over time. Once you know sex's for sure you can do a final adult home for each and save on all those upgrades saving lots of money over time.
