they are a small cephalopod, (5cm) endemic? to hawaii, From what i gather they have light producing bactiera living in symbiois within two ventral organs. I find them "in my back yard" at night...i live in kaneohe bay, near coconut island. they suposedly are ez to reproduce and seem to be ez to keep...(although they eat a ton for such litttle guys)
I feed my larger ones live fish/shrimp also from the bay, i raise shrimp for the smaller ones, and for the babies i go and look for crab spawns, and use a brine net
