My cousin gave me her baby RES because she said it wasn't eating and didn't have a tank to put it in. i already have a baby RES but i'm afraid my turtle's going to hurt the one my cousin gave me she gets close to it and follows it, it also seems like she wants to bite it but i'm not sure if that's what she really wants to do. The one that my cousin gave me seems a little scared and nervous because she just stays in the corner and doesn't move or eat i'm not sure about the gender since they're both still small. What should i do? Should i be worried or will they get used to each other?
