Oh no! I don't think two in the same room is bad. Heck, technically I have three (the beardie's tank is in the same room also). My plan is to either get a shelving unit or stacking vivs. All my tanks will be themed and I really love the two I set up now (still need to do the beardie's but have ideas lol) and have a couple other plans for future snakes vivs also. But they will more then likely all always be in the same room. If it were up to some of my family I wouldn't have my babies. They hate them. But I love and adore them so much, I don't care what they think. My cousin, who is one of my best friends, said she'd never come over anymore if I got a snake regardless of where it was and how it was kept. There are many others that have told me the same thing. But I have them anyway and I love them. Nothing wrong with having two vivs in the same room. Look on the DIY thread, most seem to be.
Can't wait to see photos!! Bet they are gorgeous!!
