Matt,
I was only trying to stop a helpless animal from needless suffering.
From what was written, I assumed he wanted to put this thing in his ten gallon tank. By telling somone that it is hard to get the octopus (proper grammer now
) to ink, that is assuming that all animals are alike. In my experiences with having helped someone care for their octopus, we found that it was rather easy to startle the animal for the first few months. The octopus We cared for, was housed in a 55 gallon with plenty of rockwork to hide in, and a specially constructed "house" where the animal could hole-up and be totally enclosed.
As for the habit of escape, which they are very good at, an acrylic top was latched in place. A 6 inch flap of acrylic was all that would move without unlatching the entire top. That piece was also fitted with acrylic latches, which you could move into place to keep the flap from opening.
He constructed a 40 gallon sump with bulkhead intake and outlet, and a 2 stage mechanical filtration system. A Berlin in-sump skimmer was also added.
One afternoon, he came home from work and sat down to feed the octopus. He noticed the water was tea colored but... no octopus... He used a flashlight to look all through the rockwork. Nothing there... he tapped on the glass and finally started to break down the rockwork to find the animal. But first he heard a rattle under the tank in the cabinet. He opened the doors to find the octopus sitting in the sump clinging to the skimmer, with one of it's legs caught in the Rio Pump,and it ws barely clinging to life it was so weak.
He couldn't imagine HOW the animal got through the screen over the inlet to the sump. He looked and looked. After it was recovered, and the water was changed. He returned it to the tank. The next day he was reading on the couch when he casually glanced over at the tank. He caught it just in time to see the octopus inserting its legs and then it's head right through the grate over the intake to the sump.
Turns out that (evidently) an octopus needs only to be able to get it's beak through a hole in order to fit through it. The animal can literally squeeze it's body down like a sack of jelly and fit through any hole as long as it can pull it's beak through as well. The grate was a regular intake grate. This was quickly covered with a finer grate material.
Sorry this was so long, but you see... this guy was so ready to have this animal. He took all the precautions and had a big enough tank and was home most of the time and cared for it in every way he thought he could, and the animal still ended up getting hurt.
Maybe this guy was just unlucky, maybe he needed to read up more on the animals he intended to keep.
The point is, Octopuses (correct?) Can be tricky to keep. They are not for the beginner and I just thought it was better to steer a beginner clear of such a challenging animal rather than have to hear about the consequences later and then say to myself... why didn't I speak up??
Can I get an Amen?
Sorry if my first post sounded authoritarian...
