Wild Fact #246 – Not Afraid to Pull the Trigger – Triggerfish

Triggerfish Species

Divers and aquarium enthusiasts alike will appreciate the 40 species of Triggerfish scattered throughout the oceans of the world. In fact, these colourful animals are quite popular among pet owners and scuba-divers as their colours and unique behaviours entertain people every day. The largest of the Triggerfish species is the Stone Triggerfish which is capable of reaching 1 meter (3.3 feet) in length but we are going to narrow our Wild Fact to just one species. We are going to learn about the entire family so we can be prepared to spot any one of these species during our next ocean adventure.

The “Mikey” of the Fish World

The eating habits of these bottom dwelling fish are particularly unique. You see, Triggerfish will dig up worms and crabs by blasting the sand away shooting out  a powerful stream of water from their mouths. Once their prey is uncovered, they don’t stand a chance against the incredibly tough teeth of this fish. In fact, the jaws of this creature are so powerful that they have been known to feed on Sea Urchins, which is no easy task as you need to be wary of all their hard spines. And when they are not uncovering their buried prey or feeding on impenetrable animals, they will generally feast on the smaller fish inhabiting the beautiful reefs. As you can see, the Triggerfish is not a picky eater.

Protect the Nest at All Costs

This particular fish depends greatly on the tides and consequently the moon. Their astrology side comes in handy when deciding the best time for mating. When everything lines up just right, a large group of Triggerfish will congregate on common mating grounds. The males will typically set up their territories and create nests capable of housing over ten thousand eggs. As you might expect, the males are quite protective of their territory. Actually, they are known for how aggressive they will become to protect their nest. These large fish with strong teeth have been known to charge and bite anything that comes near their territory. Yes, this includes larger fish and even humans…so be careful during your next dive.

  1. the general rule for swatalter fish is 1 type of breed per tank so u could have like 1 clownfish and 1 tang with a whole buch of other fish just not the same breed except for damsels because they arnt really all that aggressive and u could get like 4clowns 2 it jsut depends on the size of your fish tank and if your a starter i recomend getting a used 10gallon and just keep live rock and a few soft corals and keep like 3-4 damsels because they are pretty hardy fish.
