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.

 

Accidental Harbor Freight tarp pond on top of a compost pile

I put this blue tarp on my compost pile, hoping to stop weeds from growing in it. It didn't leak, and the rain-filled it up. Then the rains came and filled the tarp with water. The Mosquitoes took over. To control the mosquitoes, I added a few guppies. I added some duckweed for shade and to take care of the ammonia. The guppies proliferated, and their colors popped. When summer came, the water was to shallow and got too hot for the guppies, and  I moved the guppies to a 110-gallon stock tank I got on sale from Tractor Supply. The stock tank pond changed the character of my back yard garden and produced some great guppies.

Ten Gallon Fishless Cycle

Note the color of the SeaChem ammonia indicator. There is enough ammonia in there to kill a fish. The plant is hornwort I bought at PetSmart to seed the aquarium with nitrifying bacteria. The rock I collected from Two Run Creek in Georgia. The gravel is PetCo store brand I got on sale. For filters I am using an ATI foam filter and a Hagen AquaClear hang on the back power filter. The canopy, striplight and heater are DeepBlue.  The aquarium I got almost free from Craigs list.
