Care
Picasso Triggerfish require a spacious aquarium to accommodate their active swimming habits and potential territorial aggression. They are best kept with other semi-aggressive fish and may not be suitable for a community tank with peaceful or small species. A varied diet of meaty foods, including shrimp, squid, and fish, will keep them healthy and vibrant.
Reproduction
In the wild, Picasso Triggerfish are known to be nest builders. The males prepare and guard the nesting sites on the ocean floor, where females lay their eggs. The reproductive behaviors of this species in captivity are not well-documented, making breeding attempts by hobbyists quite rare.
Habitat
Native to the Red Sea and the Western Indian Ocean, the Picasso Triggerfish can be found in shallow lagoons and coral reefs. They often inhabit areas with plenty of live rock or coral formations that provide shelter and territory for these robust fish.
