I actually separated my two after experiencing a few small probs, 1 being that they are both males but my eldest wouldnt leave my youngest alone, forever chasing him around the viv. Plus now they have been separated for a while, I find it allot easier.
When housed together its difficult to resolve possible problems (passing of feaces) plus, if one of them was to be sick & I wasnt around, you dont know which one it came from. Since separating them I find it allot easier keeping track of them individually & I believe that as a snake owner it is essential to be responsible & know that you are providing the best enviroment possible for them .
Allot of people find housing their snakes together works well if they are of the same size & experience no problems. I also noticed on the RSPCA website earlier that on the care sheet it says that it is perfectly 'ok' to house together..???!!! its a very sticky subject really, (on every forum) but its worth a try housing them separatley, surley? if its for the general happiness of you snakes.
Good Luck
