Hello I'm new here and I'm also new at taking care for turtles

, I have been searching about red ears sliders since last week and I found this forum so I thought you guys could give me some advice since some of you are really experienced

. I also want to know what kind of food I should give to my red ear slider to keep it healthy and I also was wandering if I could put him/her in a 30 gallon Rubbermaid pot that I have in my storage he/she is about 2 inches my friend gave it to me because she didn't have enough space he/she was in a 5 gallon tank with 2 other turtles

, the tank was covered in eagle

and the turtles didn't seem really happy

. she/he was the smallest one and seemed really unhappy and shy she/he is also missing her/his front claws is that a problem

?
Anyway thank you .
