1. Wrasses are very lively fish, and love to jump. You should always have a well secured lid when keeping wrasses in your aquarium.
2. It is not a good idea to wash your filter media with regular tap water. The tap water can kill the beneficial bacteria that is built up in the filter. Use distilled water to clean out your filter and its components.
3. When you are picking out fish for your aquarium, you should always pick the best specimens available to put in your aquarium.
