Humu Picasso Triggerfish

[Cris]

Hi, I have  a Humu that is about 31/2-4 inches long.  I have had him since he was tiny.  He is not aggressive to tank mates except snails and hermit crabs.  I have read that as they get older they can get very aggressive.  My tank is 120 gallons and there are fish much smaller than him that he has never bothered.  Anyone ever have a bad experience with this fish as it got older?  I would hate to have to rehome it.  Thank you for any advice

Each fish has a unique personality but yes, they do get more and more aggressive as their space decreases and they claim more territory. The larger the fish the more space it wants and the easier other animals become to eat as well.  I have had them in the past (way back nearly 30 years ago) in predator tanks and the triggers always started to eat the tank mates and some even started to attack equipment in the tanks.  I remember one store that I used to go to that had triggers in this genus that would shatter heaters in the tanks and one even bit the finger of an employee.

Hi Dave, 

 

Hope you and your family are doing well and thanks so much for answering.  Yikes, he has always been great but maybe I better rehome him to someone with a bigger tank.  He is about 4 inches and I would hate him to eat his tank mates.  Hope to see you at a meeting one day when it is safe.  Cris
