good pond

not nearly as one would think. My thoughts are if you are going to build one, why not go for it and add reall girth to it... maybe a couple thousand gallons...

what is your location?
 
There are actually quite a few fish you can keep in ponds, especially in your area. Topminnows and some other killifish, many livebearers, paradise fish, golden shiners, rosy reds, mudminnows, and banded sunfish (Enneacanthus) are all possibilities. Your options are wide open with plants; just visit a local pond center, nursery, or home improvement center to see which plants you like.

To answer some questions from your other thread- you can keep predatory fish in a relatively small pond, but you're going to have to feed them just as you would in a tank. You only need a giant pond if you want a self-sustaining system of predator and prey fish.
 
i have decided to go with a 450 gallon pond.

is that big enough to have predator and prey fish???
 
It is probably big enough for five or six small (4-5") predators, and a fecund prey fish such as rosy reds. The predators will need supplemental feeding until the minnows get busy; it might be a good idea to get the minnows going first, then add the predators a few months later.
 
that is what i was thinking. how many minnows would i need before i should put the predetors in?

also which is the best way to breed rosy reds? should i put the pregnant fish in a seperate bowl???
 
I would start with about a dozen fish; that way you should be sure to have plenty of both sexes, but they won't feel overcrowded in the pond. Get extra in case of mortality; feeders are usually in pretty poor condition when you buy them.

Sink some clay flowerpots or other 'cave' structures in the pond, add the fish, and they'll take care of the rest. Rosies are not as bad as guppies about eating their young, but it's still a good idea to add some submerged plants (anacharis, hornwort, etc.) for the little ones to hide in.

Goldfish flakes will do fine as a staple diet, and they will also eat algae, aquatic inverts, and insects and leaves that fall into the pond. It's more important to feed the fish early on before small aquatic organisms get established in your pond.
