Yes, because they are very small, so they adapt to coral easily. but keep in mind... There are many types of Mandarin fish and the most popular do like to have "rock" cover since they tend to be smaller fish. Mandarin fish do not live in coral but may live among the coral. Keep in mind that coral are living organisms. If you have a Mandarin in a fish tank, then make sure it has a hiding place. It does not have to be a piece of dead or live coral. It will feel more comfortable. And making sure you feed it live food at certain times of the day, you maybe able to train it to come out for you.
