I believe you are wrong on the plural form, my friend...but at any rate the exact species is not known. It was not available from either the LPS
nor their distributor, which has caused a bit of grief to say the least. The best I can do is tell you that it is not a dwarf octopus and is much more inclined to be nocturnal unless it is VERY hungry. Trying to work on a quality photograph but as she spooks easily that has proven to be very hard to do, even 4 months after having her. And especially seeing as she has barricaded herself into a cave.
I'm trying to post the tank specifics on my signature but am not having any luck including anything other than a quote.
