What trace elements are needed for keeping clownfish?
To keep marine fish, of course you need "seawater," and natural seawater is certainly the most suitable for keeping them, but due to environmental pollution, using seawater drawn from the seaside is not the most appropriate approach; instead, seawater should be drawn from the deep ocean far offshore, and this seawater drawn from the ocean must undergo many processing steps before it can be used. First, the container holding the seawater must never be a metal container, because the metal ions will dissolve into the water and harm the health of the aquatic life. Second, it must be sealed and stored in a place not exposed to sunlight.
