A brilliant lemon-yellow body, sharp black-and-white \"fox face\" mask, and impressive size make it a true display fish. As a bonus, Foxfaces are voracious algae eaters and will keep nuisance hair algae, bryopsis, and turf in check across a 100+ gallon reef.

Always wear thick gloves and use a fine-mesh soft net. Avoid trying to grab the fish by hand. The venom is not life-threatening to a healthy adult but the sting is painful and the area can throb for hours. Soaking in hot (not scalding) water for 30 to 60 minutes denatures the venom.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is mine showing dark blotchy markings?\u003c\/strong\u003e\u003cbr\u003e\nThat is the Foxface stress and sleep pattern. Newly added fish wear it for a few days; healthy fish slip into it at night and snap back to full yellow as soon as lights come on.
