Congrats on the snake. We currently have 7 snakes; White-side Eastern Black Rat, Taiwan Beauty Rat Snake, Northern Pine, South Texas Bull and 3 normal corns. Everyone except our baby corns (which are about 8 months old now) are in 55g tanks. We did the same thing Wode did... Craigslist specials for stupid cheap.
We have things for our snakes to climb on and they seem to use them, our snakes will go clear to the top of the tanks. So I wouldn't worry so much about having "unused" space. She will use it, maybe just not as often as you would like. She will be thankful to have all that EXTRA room to stretch out in!
We use clear plastic "shoe box" containers for the larger snakes and heavy ceramic dog bowls for the smaller snakes. We also use coconut hides (extras from crab keeping) for the smaller snakes. We use aspen shavings as bedding for our snakes *which they can use as cover as well as hollowed out log pieces, but only for our larger snakes.
We feed f/t for all of our snakes. At first our baby corns were eating live, but we buy frozen mice in bulk because its cheaper. So we switched them to f/t by tease feeding. We only had to do it a couple of times, but they took to it no problem, of course they are not as old as your snake, so... as Wode said, there are a lot of different ways you can do it.
As far as feedings go... we do in tank feeding. HOWEVER, we don't just open, toss and close. We are sort of "sneaky" about it. Our daughter is in charge of laying out the meals for everyone (well NOT everyone, just the snakes
). My husband gets each snake out and then leaves the room with them. While he has them out, he checks them over for any issues that we might now notice when they are in their tanks and then handles them for a bit. While he is doing that... that is where my job comes in.
I go into the tat room and drop their meal in the tank, then I leave the room and my husband comes back. That way they aren't associating opening the tank with dinner time. They get to come out, be handled and then they have a nice surprise when they go back in the tat. We do this with ALL of our snakes and it seems to work out well. Then only time that this method of feeding is NOT used is when we know the snakes are getting ready to shed and they are not out and we KNOW they are hiding. For these times we simple open and drop, and wait. So far all of our snakes WILL eat even when they are super blue, even the babies.
Our corns have never attempted to bite. I wish we could say the same for a couple of our other snakes.
Our Southern Texas Bull is EXTREMELY temperamental! Bull snakes are notorious for being "bad apples" when it comes to aggressive behavior. They look and act a lot like a rattle snake. For this reason wild Bull snakes are often killed do to mistaken identity.
Norma Jean (bull) has bitten my husband on at least 4 occasions and she bluffs like crazy. I'll have to see if I can find a pic of her when she is being a psycho and post it. She is small, so, her bites are nothing and don't draw blood. She has actually struck at my husband and me more than she has actually connected. She strikes but hits with her nose not an open mouth. The only other time any of our snakes has tried to bite, we are pretty sure that the snake was sleeping when my husband reached in to take him out, and he didn't connect, just a strike. I am NOT a snake handler in my house! I like the idea of handling a snake more than I actually like it. I will hold the corns and our Northern Pine without to much issue.
I will try to get some pics uploaded so you can see some of the ones we have if you would like.
We love to share and show them off. Again congrats!
