Does anybody have any care guidelines for the Common Tropical Octopus? I hear they are a smaller species whose tentacles reach a length of 6", and that its total span is 12". Aparently, these octopi can be kept in a 30 gallon, hence my intrest! I also need to know where a dealer of this species is. ANY input would be extreamly helpful. Again, thank you....and GREAT site!

Hi,

I think there must be some confusion here. Octopus cyanea is a larger octopus (body to at least 6 1/2", arms to at least 31 inches) and is found around Hawaii and the Indo-West Pacific region. That means we don't see it here in U.S. much.

It's difficult to find a small tropical octopus on sale here. Since the local fish stores don't know their species. they can't really tell you what you're getting. If you want a wild-caught octopus, spring is the time to try for a young one.

thanks. I guess I should listen to the professionals. Just for informational purposes, this information came from The Marine Aquarium Problem Solver by Nick Dakin. Tanks, I mean thanks!

Clownfish, this just proves that you can't trust everything you read in books. There is no such thing as "just like any other octopus" - different species have different requirements. There are octos that require very cold temperatures, like the ones Jean keeps in New Zealand. There are tropical octopus, and many in between. I have never found a totally accurate description of octos and their care in general aquariium books, even those about reef aquariums.

I've kept a few O. cyanea over the years and they have three things going against them. 1). They do get big. In several months the 3 cm juvenile that you start with will have a 10 - 12 cm mantle and an arm spread of 50 cm. If it has a large tank and continues to grow, they can reach much larger size.

2) They produce huge amounts of ink. and Adult can turn a 200 gal tank completely dark.

3) They bite. I think I've posted before my story of one that got loose on a flight from Hawaii to SFO. Trying to put an unhappy octopus back in a small-mouth container with screaming flight attendants and blood running down your arm makes for an interesting flight.

On the positive side, few octopus can rival a small O. cyanea in the range of colors, patterns and textures that they can assume.
