am certainly no expert on corns as ive only had mine for 2months, but from reading alot of the posts on here it seems there is no difference between sexes, no difference in temperement anyway, just that one lays eggs and one doesnt lol. evryons right in suggestig doing ur hoework on corns before getting one, else u might find urself posting questions every 5mis, which im guessing no-one minds but it'd be a lil time consuming for ya.
as books will suggest, ur basic starter kit seems to be a cage not much bigger than ur average shoe box, a UTH (under-tank heatpad), some substrate (bedding) of which newspaper is the best and easiest and cheapest, yet not the nicest looking, and then u need a hide and a water bowl. Get ur snake and some food for it, and with all ingredients mixed properly u'll have fun and laughs and a nice new snake!
In UK baby corns range from around £30 to £80 depending on morphs (colours basically) and a whole kit from a decent 'privately owned' pet shop should be around $60 to £120. I say privately owned because it seems that huge pet store companies are bad news.
Enjoy ur snake and hope this helps!
