If a newly introduced Yellow Tang refuses prepared food, what practical first step might temporarily shock a starving fish into consuming plant matter?
Offering a small piece of fresh, plain green lettuce (like romaine) underwater secured to a rock
When a new tang refuses food due to stress or preference, immediate action is required because these herbivorous fish lack large energy reserves. If the initial offering of high-quality marine algae is ignored, a sometimes successful, though not long-term ideal, tactic is to shock the fish into eating *any* plant matter to serve as an energy bridge. This can involve briefly securing a small piece of fresh, plain green lettuce, such as romaine (ensuring it is free of pesticides), underwater near where the fish is resting. This temporary measure aims to stabilize the fish while the keeper continues to introduce the preferred staple foods like nori or spirulina pellets.
