Triggerfish is also known to be one of the smartest fish species around with this view shared within the group of experienced marine hobbyist who has kept them before as pets. They are known to be able to grasp simple pet training to perform some of the coolest tricks like swimming through hoops and although I’ve never seen one being performed before, what I know is that they are known to be able respond to signals and make some peculiar noise by grinding their teeth to denote that they understand and acknowledge your intention. But NO, they don’t bark like a dog does but that is somehow enough to convince some people to try and experiment it out themselves. Some triggerfish are very tame in the sense that they can get pretty close to their keeper (up to the extent of allowing belly rub) but somehow, there are also reports of triggerfishes attacking and biting their owners and injuring them with their strong jaw.
Caring for the fish is relatively easy and simple and the minimum requirement is that you must have at least some knowledge in marine fishkeeping. Triggerfish can be kept in a community tank comprising of different marine species like angelfish, tang and damselfish but care must be taken to ensure that the space you are providing to them is large enough to avoid overcrowding. Anything below 50 gallon aquarium size for one single triggerfish alone is deemed not suitable. Like what was mentioned earlier, Triggerfish also has very unpredictable temperament as they can easily turn against their tank mates, attacking and killing them even though everything was just fine earlier before. They are particularly aggressive during the mating period as they are known to defend their nest from intruders. Fine examples would be the Queen Triggerfish which is notorious for attacking unsuspecting divers encroaching close to their territory. When it comes to diet, they will accept just about anything but varied diet should be supplied from time to time and the best environment to grow them must have a supporting refugium system to cultivate life foods.
