  • Notes

    The behavior of the Humu Picasso Triggerfish is similar to that of the Clown Triggerfish and the two often make great tank mates when added at the same time. It can be kept with corals and anemones in a predator reef aquarium or in a fish only aquarium with other aggressive fishes. The Humu Picasso Triggerfish will eat shrimp, clams, snails, and small fish. The Humu Picasso Triggerfish will often become more aggressive as it matures. Like the family dog, this fish is not shy about begging for food, and will even eat out of your hand. 

    The Humu Picasso Trigger is best kept singly but may be kept with other triggers such as the Clown Trigger. It is more aggressive than Bluejaw Triggers and Niger Triggers. Adding all triggers together will reduce any territorial disputes. Provide with several hiding places where the Humu Picasso Trigger can retreat to. As with all triggerfish, the Humu Picasso Trigger will wedge itself into a rock when it sleeps and lock itself in by raising its dorsal fin. This defense mechanism makes it difficult for predators to attack it while it is resting. 


    Water Chemistry:

    Maintaining Ammonia at 0 ppm, Nitrites at 0 ppm, and Nitrates below 10ppm will help to keep your Humu Picasso Trigger happy and healthy. We recommend doing a water change soon after Nitrates rise above 10 ppm. Maintaining proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing), and magnesium levels (1260-1350 ppm) will help to keep pH stable in the 8.1-8.4 range. We recommend a specific gravity of 1.024-1.026 with 1.025 being ideal for fish. Temperature should remain stable as well and should stay within a 2 degree range.

    Feeding:
    Offer the Humu Picasso Trigger a mixed diet of mysis shrimp, silversides and other meaty foods 4-6 times per week. Soaking all fish food with vitamins will help keep your fish healthier and make them less susceptible to disease. We recommend soaking food in garlic as well when adding new fish and whenever your notice ich or other disease in the aquarium. Garlic will help repel external parasites and will boost the fishes immunity.

    Remember to feed slowly. Leftover food will cause nitrates and phosphates to rise. If you see food falling to the sand bed and into the rocks, you should feed slower and give the fish a chance to eat before adding a little more. Using a turkey baster allows you to target food to different fish. For example you can feed the aggressive fish on one side of the tank and then squirt a little bit on the other side for the less aggressive fish. This way all the fish get a chance to eat enough.
