1. When keeping aggressive species of fish, it is best not to introduce peaceful species of fish among them. Aggressive fish will tend to bully the more peaceful fish. Make sure to thoroughly read about the compatibility of the selected fish for the aquarium.
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. Make sure to keep a log on hand to update any changes in the aquarium. This will help you keep track of changes in your aquarium much more easily. Keep your aquarium log in a place where you wonít forget it.
