1. Some people go by the ìinch of fish, gallon of waterî rule when deciding on how large of an aquarium to buy.† This is a completely false and bad method to go by, you should always check your individual fishís tank requirements.
2. You should always purchase the correct lighting setup for your aquarium.† Doing this will make the habitat much better for the fish and plants in your aquarium.
3. When you are picking out fish for your aquarium, you should always pick the best specimens available to put in your aquarium.
