Corals and anemones
Only the corals and anemones with a known risk are listed.
No known problems with the corals and anemones in this guide.
These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.
Quarantine and health
Needs sand in quarantine to bury in, or a container of sand.
New fish are the most common way disease gets into a reef tank. Quarantine every fish in a separate tank before it joins the display, and choose a method that suits its tolerance of copper.
Captive-bred or wild?
Wild-caught.
What does it cost in the UK?
about £42. This is one UK retailer’s listing on 21 October 2026, not a market average, and every item was sold out on that day.
