Raising Guppies Outdoors in a Tuff Stuff 110 Gallon Stock Tank/Tub

The guppies are about three months old and were put in the tank when they were about 1/4 inch long. I don't really need to feed them but It gives me a chance to get a good look at them. I recently posted the only video I have of this tank for 2015. https://youtu.be/xRopyWJS7Ps A red Shouldered hawk got my breeders and about they only thing that was in the tank this year was a hand full of surviving Sunburst platies and a huge number of golden mystery snails.
