Is there any online store that sells baby bimacs?

Unfortunatly not anymore. Octopets used to but they are now gone. You can get O. Briareus from this site: http://members.aol.com/dropnet/InvertPriceList.html.

Is Octopus briareus notcurnal? Tropical? Lifespan? How large and what size tank?

I posted in the Octopus Availability thread that Marine Depot had some tank raised baby bimacs in. I'm sure they are gone by now but you could try them.

Is Octopus briareus notcurnal? Tropical? Lifespan? How large and what size tank?

50 Gallon would do...at adult size they reach a mantle length of 12 cm. (4.5 in.) and a tentacle length of 60 cm. (2 ft.) with a total of approx. 2 1/2 ft. I believe their tropical because their native to California coasts and Florida. They are known especially for their long tentacles and known as Carribean Reef Octopuses.

Toms Carribean had 11 of them in stock last week...but just got updated today and now only 1 is in stock unless its already taken which I assume. He sold 9 of them today in less than 5 hours. Good luck.

O. briareus in California?

Are bimacs larger than O.briareus?
