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 require a PH level of around 7.5 to live comfortably. Use PH testing strips to ensure that the levels in your aquarium are just right.
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.
