Humu Picasso Triggerfish (Rhinecanthus aculeatus)
 
Picasso Triggerfish

Scientific Name: Rhinecanthus aculeatus
Family: Balistidae


About the Picasso Triggerfish

Species Type: Saltwater Fish
Category: Triggerfish

Care Level: Moderate. Healthy specimens are frequently available for purchase, but stress in shipping does sometimes occur. Will accept dried foods after settling in, but frozen foods or algae grazing sheets may be required initially. After proper quarantine and acclimation to the display, this fish is generally resistant to disease. An overall good choice for the new saltwater hobbyist.
Origin: Indo-Pacific
Compatibility/Temperament: Triggerfish are not considered a "reef-safe" fish by any means. If successfully acclimated, they can be an aggressive fish. They should be given plenty of both swimming room and hiding spaces. They do not fare well in a reef environment. They will generally mix with other non-reef fish, but will snack on reef-creatures such as snails, shrimp, crabs and mollusks.

Ideal water parameters for Picasso Triggerfish

Marine fish are highly sensitive animals with very specific care requirements. Most all saltwater species will require similar water conditions, designed to replicate that of natural seawater. Ammonia and nitrite levels should absolute zero, temperature at 76F to 80F, and salinity at 1.024 to 1.026. Although some fish are tolerant of lower levels of Nitrate, the goal in every aquariums should be to keep Nitrate as close to zero as possible, and certainly under 20ppm. Finally, maintaining a stable pH of 8.0 to 8.4 is desired. Achieving this is made easier by monitoring alkalinity, which should be kept at 8-12 DKH, and calcium, which is targeted at 400 to 460ppm.
