Guppies In a 110 Gallon Tuff Stuff Stock Tank

I started raising guppies outside last year. It's incredibly easy to do. You really don't have to feed them but I like to so I get a good look at them. I started out wit a tarp over a compost pile that kept getting full of water and mosquitoes that I put some guppies in to eat the mosquitoes. They grew fast and when I found the 110 gallon stock tank for sale cheap at Tractor supply I just had to give this a try. There is no filtration. The stock tank gets full sun and its full of plants. The only maintenance is keeping it full of water from the hose. If the water gets to green for me I let the hose trickle into the tank until it clears. The green water does not harm the fish but you can't see them if it gets to bad. This only happens in the spring before the plants get going.
