I think I got enough background info for the basic care of a rose hair T. (diet, substrate, enclosure, etc.) This will be my first T and the only thing holding me back from actually purchasing one is that I'm wondering how sudden their movements are/ if they're likely to try dashing to make a mad exit when I lift the lid off to clean the viv. Are they generally a calm species, or should I be worried of sudden and quick movements? As well, I own two rats and while I'm sure it'll be fine so long as the viv is securely sealed at all times, is it safe to keep a tarantula viv and a rat cage in the same room? I don't want to risk my rat's lives. Thanks.
