I have to disagree, there is a person on this board that moves their nano tank 4 times a year in and out of their dorm room at college without issues. Done correctly on this small of a tank and only 3 blocks away IMO won't cause any problems. BTW I am constantly rearranging things in my small tanks to frag, to clean, to move corals that are getting too close and so forth. I LOVE my small tanks and don't buy into the bigger is better concept. Yes, I will concede that smaller tanks take more care in that things can go wrong quickly because of a smaller water volume but the trick is to do your weekly water changes faithfully and test your water. The only problem I ever had was a bad batch of water that I bought from my LFS but a few small daily water changes got my testing back to normal in no time with no ill effects to my corals or fish.
I imagine there are all sorts of reasons why a person would choose smaller tanks such as expense, space, or as in my case just a desire and fascination with anything on a small scale. I have 5 tanks, all under 30 gal.
