Undulate Triggerfish
Balistapus undulatus
The Undulate Triggerfish is a truly stunning fish appealing to all due to unusual markings and curious nature, it will recognize its owner after a time and beg for food. Should only ever be housed singularly as it is aggressive towards other triggers. The undulate has been known to bite when cleaning the tank, so keep an eye out.
It requires a tank of 200 litres or larger with plenty open water for it to swim in and live rock to hide in, it may on occasion rearrange the rockwork in the tank. Trigger fish aren't reef compatible and will attack any invertebrates with the exception of stinging anemones. Triggers will eat meaty foods like clams, lancer fish, brine shrimp and hard shelled crustaceans to help wear down their teeth. They usually adapt well to frozen and even dried foods.
Approximate Purchase Size: Small 4cm - 6cm, Medium 6cm - 8cm
