Hi everyone! I'm new here and I guess that this is the best place to ask for red eared slider help. I got a red eared slider for Christmas and since I first got him on Dec. 25th, he has never eaten. Ever. He also has never basked. All he does is sit in a corner of the aquarium. The water is 80 degrees and the lamps are setup to warm the basking spot pretty well.
I move him into a bucket everytime I want to feed him (so there's less of a mess in the tank) but he never eats. I've tried giving him kale or turtle pellets but he just sits in the corner

Any ideas on what's wrong? Will he die because I've never seen him eat or bask...
