guppies pond size??

hey thought id ask the pond gurus about this. i have about 150 guppies. many fry juvies and breeding adults. they were all in a 20 gallon in the beginning. what size pond would they be happy in ?? dont mind them reproducing more and more.

i could dig my backyard and concrete. or could a tank aquarium suffice??

You can get larger tanks for your fish but sooner or later you must decide how many you want and have the room to care for. As a starting point, you might want to try a container type pond. It would allow you to find the right mix of sun and shade to control temperatures to reasonable values. You could find out whether there are birds or other things that will control your guppy population or even decimate it. If I recall correctly, rain is a very common event so you need to learn how to control the water levels. It will let you experiment with plants and planting water depths by using supports to hold the plantings up off the bottom. Concrete can be a bit harsh as the final layer in a pond because concrete is made using lime among other ingredients.

Im actually setting up something very similar, a guppy & plant grow-out pond. Its a 110 gal container pond that Im going to set up on my porch. Right now Im using a 50 gal rubbermaid; it works but its getting pretty bent out of shape from the water weight and Im starting to worry about its integrity. If you want to go the container pond route google Tuff Tubs, I found them on here and thats what Im going to use, I got mine for $75 shipped. They come in a lot of sizes so you could go smaller or larger if you wanted. There is another post here in the pond forum from some one using them.

When I was a kid I dug a hole in the backyard, till I got tired. Probably 30 gallons. Lined it with plastic and filled it with water. In went the guppies from my 10 gallon. At the end of the summer I had 73.

On the other hand, the old Royal Waiakoloan hotel had a large reflecting pool, probably 35000 square feet, with guppies in it. They kept a pair of Oscars in it for population control. Makes an interesting display if you have the room.

Most large cities will have pond supply companies, and these will have containers which are purpose made. Like Tuff Tubs, you won't have to worry about water weight deforming the container.

You need to decide on a target population as guppies will overpopulate themselves if left unchecked. I would then calculate it to the inch per gallon rule as numbers will fluctuate frequently it would be the safest way. Once the pond is built you then need to decide whether to use a heater or let nature take its course, if you choose nature then you will need to take temp timings for a week every few hours t find average temps at different times of day and night. There are plenty of people who do keep guppies outside as they are so easily looked after.
