LOL, Google aquarium and MTS the acronym is well known and established at almost the same time as the saltwater hobby
Before I suggest a place to look you MUST always keep in mind that most vendors and virtually none of the people that buy imported animals (al though LA is getting better
) do not have any clue as to species. You will have to accept and care for whatever you get and try again after it expires if the wrong animal arrives. That being said, WHEN they have octopuses,
SaltwaterFish will often have hummelincki. I believe most of their stock comes from Haiti (or did before the earthquake) and they are quite common there. Lately, aquacon has shipped one to
teacherKim. I hesitate to recommend this supplier because of past issues but I believe there are two from them within the last year (I would still avoid purchasing anything else from them and be aware that their guarantee is to replace items on your next shipment, not a refund or a reship). Any place you see a
Caribbean Two Spot octopus for sale is likely to be selling a hummelincki but you will also occasionally see it listed as a Bimac (the trick is to call and ask where it was found, often it will be the Caribbean as it is not legal to sell bimacs caught in CA and that is the main source).
Additionally you can look in the List of our octopuses (the combined as well as this years) at the top of the
Octopus Journals and Photos subforum and use your browsers find feature for the word hummelincki. When I know the source it will be listed (and linked in the 2013 listing). O. hummelincki has been hard to find in the last few years but we are seeing many more in this last season. Be aware that, in the past, we have seen the females brood quickly after being introduced to the aquarium. I think this is more a result of it being easier to catch because it is hunting more frequently in preparation to brood than anything to do with aquarium life but it does anecdotally seem to happen frequently. O. hummelincki is a small egg species so raising young is not a home tank viable endeavor.
