well, a "slider turtle", or a red eared slider always has a red line where their ears would be. that's obviously how they get the name!
Red Eared sliders are aggressive over food, territory mates, etc. Most likely it was due to that aggression. I would suggest separating the sliders and taking the injured slider a vet. Good Luck!
NO ! Since it would NEVER come across such an unsuitable food in the wild !
Nothing would happen. You would just get a lot of calcium.
A 17-inch red-eared slider would probably hold the Guinness World Record for biggest red-eared slider turtle. A very large adult red-eared slider is a little over a foot long from the tip of the nose to the tip of the tail, with a shell around 8 to 9 inches long. A more average size (especially for males, which are generally smaller) is around 9 to 10 inches from nose to tail, with a 6 to 7 inch shell.
the "red eared slider turtle" would be the best one because they can live up to 50 years!
They can be housed outside, yes. Just make sure they have everything they would get from an indoor enclosure.
you shouldn't keep sliders with ANY kind of lizard
I'm sure it would. But a RES is not dumb. If they get too hot they will go back in the water.
