Help Needed!!! Red Eared Slider In Trouble!!!

[Nicky]

hey everyone,
I posted this in another thread but i'm realling getting desperate so i'm gonna post it again with its own title. Ok well first of all, I need any info at all housing lighting so on about red eared sliders because my friend houses his in a 10 gal tank with no filter it literally lives in its sh*t. Its shell is peeling i think thats shell rot and its shell is bumpy which is a bad sign. I know its horrible and i can;t stand to see it like that. Acouple weeks ago i was talking to him trying to reason with him about what he was doing and to take better care of it, i even offered to pitch in for new tank and filter but he just ignored me and said its his only friend and blah blah because he thinks his life is over cuz his girlfriend left him and hes being really stupid about it just because hes feeling are hurt is no reason to take it our on animal anyways I'm hoping that he'll either clean up his act sell it to me or if not could i call human society or would they do anything? If he gives it to me i wanna be able to house it. I saw a pic on this forum ahwile back of someone housing there slider in a big black sorta kiddy pool with plants and stuff i was wondering how much one would go for and could they climb out?( how high should sides be). If human society take it what will they do with it. because i think i could find acouple of people i know how r really good with turtles to take him. And the heart breaking part is its been living like this for 12 years isn;t that disgusting. Plz any help would be great
