1. 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.
2. When starting out a new aquarium, it is best to add hardier species at first. Once your aquarium ages a bit and gets settled, you can start to add more sensitive fish to the aquarium.
3. When adding plants to the aquarium, be sure to check the lighting needs. Try to find plants that will fit the pre-existing lighting conditions of your aquarium. You should avoid plants that require much more light than the fish in your aquarium.
