Can anyone give me some general information on these two octopus? I've heard of O. Rubescens living together in schools during their planktonic stage. Does this carry over into the other stages of their lives? Where can you get Cyanea? Other than a chiller for Rubescens are there any specific needs for either of these species?

O. cyanea gets too large for most aquarists to consider keeping one. They are found from Hawaii and French Polynesia to East Africa, are often eaten for food, but rarely are found in the aquarium trade. We have kept a few that we captured as juveniles. Escaping, inking and eventual size were all problems.

I'm not a pro like roy or anything, but from my understanding of Cyanea, your tank is long enough but the other dimensions would make them incredibly cramped...not much wiggle rooom

Well if O. Cyanea is out, then I guess it's safe to say O. Vulgaris is a no-go as well? I'll be moving down to the Texas coast soon and if I can't get my hands on O. Cyanea, then I'd like to try my luck at catching O. Vulgaris which is common down there.

O. cyanea is not only big- it's a highly mobile animal that would get 'restless' in the aquarium, hence their tendency to escape. I have seen people try to keep them in tanks 1.5m diameter and 2mx1mx1m, and they have gotten out.

But O. rubescens doesn't get as large- and I think Roy has had good success keeping them in a tank about the same size as yours.

what tank would you put the cyanea in???
I am planning on keeping them in my current 250 gallon tank. After Bubbles lives out her life and I can secure the top of the tank I want to get a fairly large animal. I was thinking either O. Cyanea, O. Vulgaris, O Rubescens.

I'm worried about the Rubescens' tendency to bite. I want a large animal that I can interact with and not worry about injuring either the animal or myself.

I have a extra feisty octopus right now, and I do have to be extra careful when I am cleaning or interacting, but it adds an extra element of excitment. Even if I knew how evil she was I still would have gotten her. I do think she ill come around eventually, and I bet the same would be true for the Rubescens, Just takes more patience. I say try it out if you can find one!

If I do get a Rubescens I'll have to get a really big chiller lol. I really want a larger octopus than commonly found in the trade industry because I find that they are easier to interact with and not get bitten due to the fact that their arms are longer and allow you to stay further from their beaks. lol

Octopus cyanea would go mad in 250 gallons. Yes, you may technically be able to keep a lid on it, but it would probably get so banged up trying to get out it would get skin infections. O. cyanea do bite, and there's a good chance it would try each time the lid gets taken off and an arm near. Plus, realistically you're more likely to find one being sold for sushi than for an aquarium.

Any time you handle any octopus you open yourself up to being bitten. Given most octopus's speed, for animals bigger than pygmies, I don't think longer arms would make anyone significantly less likely to be bitten- there's always a chance. In most species, longer arms can be stronger too and can easily get a good hold on you to pull their mouth to you if they want (also- O. cyanea, O. rubescens and vulgaris have equivalent relative arm lengths).

I would LOVE to have some form of sepioteuthis for this tank I have now, but I don't have high hopes for finding them, and I don't want to leave the system empty until that chance happens upon me. So until then I want to try my hand at a large octopus, which is half of the reason why I got this large tank.

From what I understand, O. Rubescens is not only prone to biting, but it's bite/venom is particularly painful, at least for some people.

+1 on long arms also being strong arms. I don't see an advantage there in avoiding bites, and the bite will then come from a larger animal.

I have an O. Bimaculoides which may not be as large as you are looking for, and requires a chiller, but is interactive and not known to bite or be toxic. It's almost identical looking cousin O. Bimaculatus is larger, but tends to occur in slightly deeper water, and seldom if ever in tide pools, so while neither form of bimac is generally available for purchase, the larger Bimaculatus is harder to collect yourself. But if you can find a way to get one, and have a chiller, I suspect a Bimaculatus would be great for you.

I've read a little on both O. Bimaculatus and O. Bimaculoides, but I have a warm water tank, and to switch to a temperate I would have to get rid of all of my current animals. That's why I was originally thinking of O. Cyanea or O. Vulgaris. Also I read a little about O. Maya. Does anyone know of any species that are tropical and get between 2 and 4 feet?

Where on the Texas Gulf coast is O. vulgaris common? Very few octopuses show up on that coast, as far as I've been able to determine.
Do you mean the Flower Garden Banks, which is 80 miles offshore? O. vulgaris has been identified there.

The crab fishermen say they pull them in some times not sure where though, they said at least 30 miles out.

Octopus Vulgaris has been reported all over the Texas coast. http://www.channelviewcondos.com/photos.php?action=details&record=26 There is also another article online that I cannot locate again. The author states that he and his son went for a walk on Mustang Beach one Christmas morning after a big freeze, and found (correct me if I'm wrong) nearly 200 dead octopus. There were a few pictures I believe and they looked like O. Vulgaris. Not to mention the people that I have spoken with that used to collect around these areas that said where and when I would be able to find them.
