Goldfish
Average Size: 3-4 inches
Maximum Size: 10 inches (in the proper environment)
Food: commercial Goldfish flakes, freeze dried tubiflex worms, etc.
Minimum Aquarium Size: 55 gallons (for two Goldfish)
Other Equipment: filter, heater, and aerator
Water Changes: 50% every week
Nature: non-aggressive
Summary
Goldfish come in many varieties, but belong to the same species, Carassius auratus. Goldfish can not thrive in a bowl, as commonly thought. They need a relatively large aquarium (with filtration and aeration), as they can grow to be ten inches long. Goldfish are not shy fish. They have little to no fear of humans and are very hardy, which makes them one of the most popular aquarium fish today.

Bluegill Sunfish
Average Size: 5-8 inches
Maximum Size: 12 inches (in the proper environment)
Food: garden worms, wax worms, crickets, etc.
Minimum Aquarium Size: 90 gallons (for three Bluegill Sunfish)
Other Equipment: filter, heater, and aerator
Water Changes: 25% every week or 50% every two weeks
Nature: semi-aggressive
Summary
Bluegill, native to much of North America, are fun, but challenging fish to keep. Their aggressive feeding is fun to watch, but most of the food they eat is natural, making it quite expensive to feed them. Only experience fish keepers that are willing to take the time to suit these fish's needs should keep Bluegill. They are not for beginning fish keepers.

Summary
Pumpkinseed Sunfish care is not much different than Bluegill care, as the two fish are very closely related.

Green Sunfish
Average Size: 4-6 inches
Maximum Size: 8 inches (in the proper environment)

Minimum Aquarium Size: 75 gallons (for three Green Sunfish)
Other Equipment: filter, heater, and aerator
Water Changes: 25% every week or 50% every two weeks
Nature: semi-aggressive
Summary
Green Sunfish are very aggressive feeders due to their relatively large mouths (larger than that of a Bluegill or Pumpkinseed Sunfish). They are slightly smaller than the other sunfish, enabling them to be able to live in slightly smaller aquariums.

Koi/Common Carp

Minimum Aquarium Size: 75 gallons (can only be housed when young)
Other Equipment: filter, heater, and aerator

Summary
Koi or Common Carp can grow very large and should be kept in ponds when they reach adulthood. When they are small, they can be housed in large aquariums. Carp, like Goldfish, are very dirty fish and you will need to clean your aquarium water very frequently. They grow very rapidly and will soon outgrow your tank, so make sure you have a pond that you can transport your fish to.
