Octopus for a 30 gallon?

HI, i'm new to the forums, but i'm already started to get addicted to octopus and cuttlefish :frown:. A while back I looked at getting some dwarf cuttlefish (Sepia Bandensis), but of course, the only source for them was quickly bought out before I even had time to click "bid".

Now, after my recent seahorse incident (my Hippocampus Reidi died from Vibrio x Gas Bubble Disease), i'm thinking about dedicating the tank to an octopus. While seahorses are still my "main thing", i'm relinquishing my 30 gallon to something else as I do not want the risk of vibrio being spread around again.

So, I guess my question starts here..are there any species of octopus that can be housed in a 30 gallon for LIFE? I keep reading different info everywhere I go. I see Vulgaris and Bimaculoides are the two "commonly" kept octopus, and are for "beginners". But, I never really see what maximum tank size is for either. One place says my 30 gallon would be okay, and another article says nothing but a 50 gallon MIN for any octopus other than blue-ringed, etc. (obviously I wouldn't risk it, but really,I have no desire whatsoever to own one).

I heard Bimaculoides gets "biggish", so i'm guessing that rules that one out.

Can anyone help me here? Any octopus OR cuttlefish possibly that can be kept in a 30 gallon? I'm not going to die or anything if I can't own one, but I have a 30 gallon that's empty, i'm LOVING octopus and cuttlefish, and I really don't like common saltwater fish like clownfish, etc. I was angry that I wasn't able to posess Sepia Bandensis, and I really hope my "dream" of owning a octopus, etc. aren't put off again. I'm not worried about care or the like..just worried about the size of my tank.

If you need any info on my set up, just ask and I can give it out!

Thanks in advance!

I think a single, or MAYBE a pair of sepia bandensis would do well in a 30 gallon. if you want an octo, you'll have to look at dwarfs, such as O. mercatori, O. digueti (not available too often in the States), etc. A dwarf would be very happy in a 30 gallon. O. mercatoris have a mantle (head) length of 2 cm. Average size (according to danthemarineman, if he does have O. mercatoris) is quarter to half dollar sized.

On, your flamingonhot! Hey, what's going on? Sadly, I also recently lost a horse due to a vibrio infection. Even sadder was the fact that he was pregnant. I did a pouch evac on his corpse, and 9 babies popped out, plus the 2 premie fry that lasted about a week...:frown:
I've given up on seahorses.

There are several dwarfs that would do well in a 30 gal system. They inlcude O. mercatoris, O. bocki, O. wolfi, O. diguite, O joubini, etc. However, all of these species are shy and nocturnal. I would not recommed them for an aquarists interested in observing and interacting with the animal they are keeping. The two commonly available species that might just squeeze in, provided that your system is rock stable are O. briareus and A. aculeatus. Both are moderate in size, interactive, and are commercially available.
