Re: pet octopuses?
I had one once, and known a few folks who have.
They are very dirty, secretive, and one of the best escape-artists, which makes housing them difficult.
1.) You must have internal filtration that they cannot get into and hide within [a challenge since they are essentially, amorphous blobs with no bones!].
2.) You must have a very secure lid to prevent escape. Most keepers leave a couple inches or more in the tank unfilled and have a tight-fitting glass top. I had one of those velcro-screen tops they used to sell for reptiles several years back. Worked pretty well, but I don't know if you can find them anymore.
3.) They like to hide a lot, so they are not much fun except feeding time. Another thing, most octopi have very short-lifespans in captivity, about 6 months to a yr...depending a lot on the species and size when caught, of course.
So they can be interesting captives if you set them up just right, but you REALLY have to like them and have a tank reserved JUST for the octopus, because you're not going to be able to keep anything else with them.
