Instructions
Decide what species of game fish you want to put in your tank. This will determine the type of environment that you will need to create. Different fish have different requirements, and you will need to research the specific ones of your fish of choice. Bear in mind that some fish are predatory while others are solitary. Fish of different species may not mix well unless you have a very large tank.
Get your aquarium. Game fish often need larger-sized aquariums than pet fish. The bigger the fish, the bigger the aquarium and some species need more space per inch than others. Realize that some species, like catfish, can grow extremely large in captivity.
Filter your aquarium. Game fish are used to clean environments so you will need a heavy-duty filtration device, and get one that has easily replaceable filters.
Choose your bottom material. It's best to choose a material that mimics your fish's natural environment, though avoid mud. Usually it's a choice between sand or rock, and, if you're getting fish from your area, you could always just collect the material locally. Be sure to clean and sterilize it thoroughly before putting it in the aquarium.
Decorate your tank. An aeration device is a good addition, as are plastic plants. Getting a daylight spectrum bulb will do lovely things for the colors of your fish, and you can have lots of fun with interesting rocks or sculptures.
Regulate your tank's temperature. Unlike pet store fish, which are usually tropical, you made need a tank chiller to mimic the temperature of your game fish's natural environment.
Fill your tank. Do it slowly to avoid messing it up. You can use tap water, but you will need to run your aquarium for a few days to evaporate off the chlorine. If in doubt, consult a local pet shop, which should be able to give you advice on using the local water to fill fish tanks.
Acquire your fish. There are several ways to do this, including going out and catching them yourself. Be aware that in some states it is illegal to harvest and cultivate wildlife. It's best to acquire young fish, as they will adjust best.
Allow your fish to adapt to their new home. Wait a few days to feed them and avoid tapping on the tank or otherwise introducing additional stresses. Their diets will depend on their species, of course.
