QuestionI have a natural pond approx. 30ft circle & 15ft deep
I would like to stock it with fish (to keep it free of bugs blood suckers etc.) I also have several large bull frogs
AnswerI believe you are asking me what kind of fish you should get.
You should get whatever you like, because that will give you the most enjoyment. Some suggestions of mine include catfish (blue, sailfin, etc.), tilapia, koi, goldfish, orfe, bass. Of course, several of these species would not be compatible. Choose your favorite and do some research on compatible species. You also need to make sure that the species you choose can withstand winter water temperatures in your area. Also, if you get plant-eaters they will eat your plants.
Most fish will eat algae and insect larvae. Whether the a fish will eat a leech depends mostly on the species of the leech. Different fish like different leeches. Frogs eat baby fish and add ammonia to the water. You will need a large filter and a strong pump to house frogs and very many fish.
