Those are very pretty fishies, Chelsea!!!!! Remember that stress is the biggest killer of new guppies. Get them past the first week and they are virtually indestructible, though.
Tequilla Sunrise fish are supposedly a variety that the breeders want to keep a monopoly on, so they will only sell males - no females. No matter - you do not need 50 new fish every month (actually more - for the female babies all start producing soon, too!). Those fish should be bright, active, atrractive and easy to feed and watch for the kids.
You can even name one "Dorothy" and no child will know the difference!
