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. Goldfish can live incredibly long periods of up to 25 years. You should plan accordingly when you purchase a goldfish.
3. It is never a good idea to add shells from the beach into your aquarium. Introducing shells raw from the beach can add harmful bacteria and potentially new creatures to the aquarium.
