1. Fish are cold blooded and very stressed by temperature changes. An aquarium heater is essential for keeping your fish healthy.
2. Almost all aquariums require biological, chemical, and mechanical filtration processes. Aquarium filters can be enhanced by adding water pumps and air stones to your aquarium.
3. Aquarium accessories such as live rock or aquatic plants can make aquariums healthier and more beautiful, but make sure that all decorative accessories you add to your aquarium are non-toxic and will not harm your fish.
4. Keep your aquarium clean by using a siphon or gravel vacuum once a week when you perform your regular water changes.
5. Testing kits are necessary accessories for saltwater aquariums to help monitor salinity, pH, ammonia, and other chemical levels.
6. Most freshwater aquariums require about 1 1/2 pounds of gravel per gallon of water.
7. First-time aquarists must remember to vary the diet of their fish. Mixing frozen or live food with dry food will keep fish healthier.
8. Use natural items such as driftwood, rock, coral, and shells to give your aquarium visual texture.
