1. Having a quarantine tank on hand is a very good practice to use if you frequently buy new fish. The quarantine tank will weed out any sick fish that could possible get into your aquarium and cause harm to the other inhabitants.
2. When you are removing a large ornamental rock from your aquarium, make sure to check all the nooks and crannies. Some fish love to hide in there and it is good to double check to make sure you donít leave one of your fish out of water.
3. You should feed your fish a variety of food and not just flake foods. Mix it up with fresher foods from their regular diet. Giving them more a varied diet will increase the general health of your fish.
