This is my 3rd octo overall. It's a Dark Purple/Brownish octo from Bali (i suspect a Vulgaris). My other octo is a CA 2-spot and it eats like crazy, chasing down local shore crabs and eating them virtually once a day & leaving me with the carcasses of course. This Bali one has eaten once in the 2 weeks i've had him. once that i've seen, so what is he eating??? i use a feeding stick to stick krill down there since the store i bought him at said he's tank raised and they claim they were feeding him krill there (also fed other animals there krill from what i could see). They told me to hold the krill at the surface and he'll get it, yet i've tried that tirelessly with NO results. he looks happy and healthy which amazes me because i can't fathom what he's eating! whenever i stick my hand in the tank his tentacle emerges from the rock he's under almost waving to say hello. he's even played tug-of-war with me whenever i use the feeding stick withOUT krill. i put 2 saltwater fiddlers from tropical water (bright orangish-red kind), 1 camel shrimp, 1 fin-fish & 2 shore crabs from local Southern California waters here and he hasn't touched any of them. any ideas? what i'm witnessing is amazing, i'm shocked he hasn't died of hunger! Many Thanks in advance!
