Thanks everyone,
Sorseress, I am doubling your finger crossing! Lynn described him in the water as being well camoflaged and looking like he had "things" hanging off of him. I think this means he can get very spikey (my favorite octo look) so that will be way cool. Since Lynn does not seek out or catch octos the fact that he was able to catch this one suggests it is a full adult entering its last stages of life. So I am trying to prepare (mentally) for this very real possibility.
We spent the day getting stuff and converting one of the reef tanks (as I said, I was not anticipating an octo this soon). We have discussed doing this several times so we had a pretty good idea what we wanted to do but it was a little sad since this little reef was my favorite looking tanks. Most of the critters went into the larger reef (that we ultimately want to convert to a Vulgaris tank) and seem to be settling in with one exception. I had four flower anemones in the converted tank and three were successfully moved. The fourth, however, may have fatal injuries from my attempt and is still in her rock in a bucket (I did not use it to rebuild the tank). This is particularly sad since she is the first one I ever cared for and had shrunken down to dime size and lost most of her color at one point. I experimented with her a bit and she grew back to about 4" (the largest of my four and larger than before she shrunk) and turned a nice dark red in the center.
I did learn that Cromis and Pygmy Angels are actually easy to remove from a tank IF you just take out all the Live Rock and everything else that would give them shelter

. These two went into my only "fish" tank that houses 6 Clarky Clowns.
Neal is making an acrylic top tomorrow (materials purchased today) and we have ordered a skimmer that should arrive within two days of the octo (the tank has a small one now but it is useless). I did a major water change and replaced most of the substrate - wanted to do that anyway - but left some to seed the new sand. The tank is over 3 years old so it should settle back down quickly.
