Haha, I probably have room for a 3 gallon but I'd hate to put a fish in a 3 gallon unless he or she had fins or deformities that made it so they'd do better in a smaller tank. That would severely limit my desk space, though, as I already have a ten gallon and a 5 gallon on my desk :p
If my brother ever takes his 10 gallon home, I could definitely get another tank :) maybe a divided 10 gallon? Lol. Or perhaps two three gallons that could fit two fish that fit the description I described above.
