Titan Triggerfish by LiveAquaria
The name of the Titan Triggerfish says it all. This member of the Balistidae family of fish is big, bold, and aggressive. Hobbyists would have to search far and wide to find another like it. In nature, it is so bold as to even attack scuba divers who may disturb it if it is guarding eggs. Also aggressive toward peaceful or docile fish, it should be kept with others who will stand up to it, and only one Titan Triggerfish should be kept per aquarium. Caretakers should keep their hands out of the aquarium.
Meeting the needs of the Titan Triggerfish may lessen its aggression to some extent. Providing an aquarium that is large enough (300 gallons or more), along with plenty of hiding places and regular feedings may help. Be aware that this large fish will rearrange any rocks and sand in the tank.

I bought this fish for my 400-gallon tank, and it’s definitely a strong presence. It’s not for beginners. I’ve had to rearrange the rocks a few times, but it’s active and seems healthy. I keep it with other aggressive species and it hasn’t attacked them. Feeding it daily helps keep it calm.

The fish is large and very bold. I expected aggression, but it’s worse than I thought. I had to move it to a bigger tank after a few weeks. It destroyed my sand bed and rearranged the rocks. Not recommended for small tanks or mixed communities.

After researching for months, I finally got a Titan Triggerfish. It’s impressive in size and looks fierce. I keep it alone in a 350-gallon tank with plenty of caves. It’s active, eats well, and seems to be less aggressive when the tank is large and well-maintained.
