Hey, I have been doing some reading about octopus or octopi and they are fascinating creatures. I was wondering if you are able to keep them in a tank or if you can even buy them. I currently keep a lot of cichlids so I do have a bit of knowledge in fish keeping. If anyone knows anything about keeping octopi could I please have some advice.. water parametres, tank size, food etc. Thanks.

Here's a few suggestions:

1. As far as I know, you can only keep 1 octopus per tank - and no other fish/ inverts - they'll get eaten

2. You'll need a really tight lid - octopus have the ability to escape quite easily - through very small openings

3. Because octopus are quite large, require a fair amount of food and would subsequently produce a fair amount of waste, you'd also need excellent filtration and a good skimmer (this is especially so considering they can release ink - which can result in their own death if a large water change isn't done immediately)

4. As for the size of tank - this varies according to the type of octopus (generally no smaller than 60gallon)

Anyway, I haven't kept cephalopods myself, so these are just a few things I've read. I don't know a lot about them, but hopefully this is of some help.

I remember reading somewhere that another concern is them inking, which would basically poison the entire tank. If that happens, you'd be looking having to do a massive water change

Also, keep in mind that they have short lifespans (2 years, I think).

Sunshine pretty much said it all, check her links.
Not for beginners or the unprepared...
I have captured them in the wild here in Florida, seen these on display in aquaria, and despite the many problems I can tell you they are fascinating in captivity. The Seattle Aquarium usually maintains a monster specimen or two for the public to view. Unless you have seen one up close, you have no idea how responsive they can be; they change color instantly and I do mean instantly; in the blink of an eye from white to blood red or dark brown. They are lightning fast, consummate predators, and smart too; they can figure things out, like how to uncork a bottle and slide an arm in to grab a tasty crab. The tips of the arms are extremely sensitive, quivering with excitement... the king of inverts and sadly a major food item across the globe; some 40,000 tons of the poor things sold in the major markets in 2005 alone, and yes, I have consumed these along with their cousins the squid (calamari) and yes, they are tasty---but much more fascinating to watch. Do visit the folks over at Tonmo:
