THE TEN COMMANDMENTS For Successfully Keeping Tropical Fish 1. Never overcrowd a newly established aquarium. 2. Do not overfeed. Feeding once every two days is adequate. Fish should finish all food in one minute. 3. Most tropical fish prefer the temperature at 78F. 4. Always observe your fish during feeding to determine that all fish are feeding. 5. Check for fish compatibility. Note any unusual marks or frayed fins. 6. Check water chemistry weekly. Ammonia is the chief killer of tropical fish. 7. Always buy fish from a reputable pet shop. Do not be embarrassed to ask if the new fish will be compatible with yours, or if your new fish has any peculiar feeding habits. 8. Give your fish a varied diet to enhance their health and beauty. 9. Once every few weeks perform a partial water change on your aquarium. The partial water change is accomplished by: a) removing the ornaments from the aquarium, b) wiping down the inside glass with an aquarium sponge, c) stirring the gravel, d) siphoning 1/3 of the water from the bottom of the aquarium (note that the     fish remain in the tank). The new water should be the same temperature     as your aquarium and should be dechlorinated before being added to the     tank, and e) changing filter material. 10. Enjoy your fish and observe their behavior and/or appearance when they are happy and healthy. Any Change in their behavior and/or appearance should be immediately investigated and followed up.
