Don't get it. I am a big fan of octopuses and I currently have a O' Vulgaris in one of my aquariums at home. A couple of years back, I was offered a mimic octopus for sale by my LFS. I told the LFS that I will think about it (due to the $ tag). I went home and found out that they do not last long in a home aquarium and the only person that was successful at keeping one alive only kept it alive for 6 months. I told my LFS that I was not interested. However, I have done plenty of research on this matter and found out that it might be possible to keep one alive if you are able to replicate it's home habitat which consist of providing the mimic octopus with at least 10 inch of sand bed in the display tank, due to the fact that those octopus burrows themselves in the sand. On the other hand, having 10 inch of Sand in the home aquaria is somewhat not possible because if the octopus stirs the sand, it will release all the bad things from the sand into the water.
