FaunaClassifieds - Alligator Snapping Turtle

hi everyone i have just recieved a baby alligator snapping turtle. i was wondering if anyone can give me a run down on how to care for it. i have been doing a lot of research on them but every site seems to give the same info about where they come from what they eat and so on but not alot about how to raise them at home. hes in a 55 gal for now (hes about 1 1/2 inches) i've been taking him out of the tank to feed him so it keeps hes water clean and yesterday was the first time i really saw him eat (some turtle food the fish shop gave me). i keep a lot of fish so i know about the water para. and temps and ph. but i was wondering does he or she did a certain ph to be comfortable in and the temp is at 75 right now. i have a bunch of rocks in there that reach just above the water line that way he doesn't have to swim to the top to get air. i also have floating drift wood and more that sinks with some fake plants as cover. i do have some small baby cichlids that he is living with but they are muts so they are food for him. so any help with him would be great since this is the first time ive keep turtles.
