[edit] Aquarium Compatibility
The Picasso Trigger can be a bit of an underwater enigma. Some individuals behave perfectly with tankmates, while others change personalities and attempt to destroy smaller or more passive species. Some more peace-loving individuals may also snap and start harassing their subordinates. That said, it can be kept with other large, potentially aggressive, species. Juveniles are more passive than adults, and it is less of a threat to its neighbors in a larger tank. It will eat a wide range of ornamental invertebrates—thus, the reef aquarium is not a good home for this fish.
[edit] Breeding/Propagation
Demersal (on or near the bottom) spawners that tend and protect their broods.
[edit] Notes
This is an active fish that always seems to be trying to figure out how to find another meal. It will lift coral rubble and shells as it searches for hidden prey, and may even rest on its side and use its pectoral fin to dig in the sand.
