Reptile & Amphibian Forums

Hey everybody! I wanted to give a little backstory and ask some questions. I hope you don't mind!
Last October, my brother (who hates and is severely afraid of snakes) found a racer in the warehouse that he works at. He put it in a cardboard box, and brought it home to me. I posted on another forum asking for ID help, and I was told that it is an Eastern Yellowbelly Racer. (I'll attach pics to see if you guys can tell me if it's 100% correct.) I handled it to take pictures for ID purposes, and it was more relaxed than a corn snake. He didn't try flying out of my hands, and he never tried to bite. I was really surprised, because I've always heard that most WC Racers are very spastic.
I was advised not to release it until spring, so i've been brumating it in my (cool) back room. I've checked on it several times, and I always make sure it has fresh water. He's still alive, and seemingly doing well in brumation, so I don't think I have done anything wrong yet.
Now for my questions. If I decide later on that I want to keep it, what would the habitat and basic needs be? (i.e. heat, size of cage, humidity, etc.) Is there a care sheet that I can reference? Another question is, what do you feed them? He seemed really small to me - between 5 and 8 grams would be my guess. Another question is, would you keep it, or release it when it gets warm outside? What would you do? (I'm somewhat of a novice at snake keeping, so if this snake would be more difficult, then please don't hesitate to let me know. I've got a Black Milk and a Corn Snake, so that's pretty much the extent of my knowledge with captive snakes right now. I've only had snakes for about 6 months or so.) Has anybody had much success with WC Yellowbellies?
Lastly, could you help me ID this snake 100% please? I'm from eastern Kansas - this snake was found in Lawrence, KS (which is in Douglas County). I don't know if it could be anything else, so if I could get some help, i'd appreciate it.
Thanks in advance, and I apologize for rambling so much!

Well, I'm from Wichita, and I've raised several juvenille racers as well as a few adults. They are not the easiest snakes to keep by any means, and definitely require some patience. I keep juvies in a ten gallon tank, make sure to give them a spacious hide, that's probably the most important thing. They like it pretty warm on the hot end. Feeding them can be a chore, I've had a few that will take small pinky mice right away, but those are few and far between. Crickets sometimes work, as do small lizards, other snakes, sometimes cricket frogs. The most important thing to do is to leave them alone when feeding them, drop the food in and leave the room. Racers are very wary, they have great eyesite, and they don't like to be hovered over while they're eating. Don't handle them much either, if they're stressed, they won't eat. Good luck, they are definitely a cool species, and Kansas racers are some of the best looking around.
