Vulgaris - Good Starter??


Larval Mass

Im seriously considering keeping my first Octopus however have no marine experience. I have been doing a lot of research and speaking to a local marine specialist who has kept them him self and feel that I could easily manage the task ahead however, here in the UK I have only come across two breeds The Blue Ringed and the Vulgaris.

I will not be buying a Blue Ringed due to obvious reasons so that leaves the Vulgaris however the size of tank is troubling me. The specialist says that a 50 gallon would house it fine however what ever I have read it says 100 minimum.

What would everyone on here recommend?

I have to wonder about the specialist's recommendation. Even for a lab environment with the tank plumbed to a very large water supply a 50 gallon aquarium would be very small for a vulgaris. They get larger (in bulk but not much more in arm length) than the briareus we typically keep as our larger octo in the states. Even A 100 gallon tank would be considered small and very limiting for movement but doable. Half again that size would be much better and even then I would recommend a nicely sized sump to keep up with the waste of these heafty eaters.

Welcome to the site, Ben!

There's an article (Click on Ceph Care articles on the home page) by Jason Scott on Keeping an Octopus, which happens to be a vulgaris. Jason is in the UK. This is an early article and much more information is now available on octopus keeping, but it might be interesting for you to look at.

D is right about the tank size.
