Hi. I have never kept guppies before. I am considering putting guppies in my empty (with snails) 5g tank.
The tank is still cycleing (for the next couple weeks) and I need 1 guppy to speed up the cycle. My lfs only has fancy guppies, not normal. Are fancy's likely to survive the cycle (with water changes)? Are they as hardy or almost as hardy as the regular guppies? I can't imagine a fish being so beautiful, and still be as hardy as guppies (oh wait...bettas

).
Is there any differences in hardiness or any other areas?
Thanks!
