Undulate Trigger

Undulate Trigger

The Undulate Trigger has one of the most unique and eye catching colouration in the ocean, and looks similar to a maze structure. This fish has an extremely attractive, vibrant turquoise body with with a maze structured set of yellow/orange lines.

This trigger requires a 400 litre or larger tank that includes a variety of liverock and caves. However, it should also be noted if this fish does not like the current rock work in your tank it will almost certainly rearrange the rock itself. This fish should not just be purchased without researching beforehand, as it needs to be housed with other aggressive or large fish to stop it from bullying any peaceful fish. 

This fish is extremely territorial and if planning to home, it needs to be the last fish added. As once it has discovered its territory, it may be very aggressive and defend the tank from new tank members. Additionally, the Clown Trigger will erect its dorsal spine when impressing an opponent or as a defence mechanism. 

This fish most certainly needs to be offered a wide range of meaty foods. These can range from small fish, shrimp, squid, clams and hard shelled foods to grind down their ever growing teeth.

  1. I love triggers but these guys are devils! Undulate Triggerfish are awesome fish to watch but do not put them with slower fish. Mine got along well with Damsels but chased my Picasso. He is in a tank by himself now after biting my Leopard Shark a few times. Be careful selecting tankmates and enjoy this fish; they are beautiful!

  2. An attractive fish but quite nasty. Will bite you if it can. Will be the boss of the tank in no time, especially when it gets older. Is aftaid of no fish. Even more aggressive then the Queen Trigger. Very hardy.
