What’s the difference between a reef tank and a fish only tank?
A reef tank’s focus is on live rock, invertebrates and live corals. Generally it has few fish; the fish should be reef compatible. The reef tank has more focus on lighting, less on filtration. A reef tank can be smaller. The focus of a fish only tank is on fish. It usually has decorative white coral and rockscapes, it may have live rock. Filtration is more important than in a reef tank. Limited lighting is needed. Deciding which type of tank to create is personal preference. Reef tanks can be stunning while fish only tanks are fascinating due to the variety and number of fish. In either case it’s important to be selective about the fish you choose for your tank.
