Thanks Walt and Nick, a bummer of a day for sure. I probably took a 1/2 cup full of anemone and tentacles out of the filter sock (which was also green) and about the same out of the skimmer. The entire house reeked of anemone, even my wife noticed. The whole green filter sock would have been comical with St Pattys day had it not been such a sad and aggravating situation. Oh, I also changed about 12 oz of carbon and within a couple hours the water was clear. I am avoiding my weekly water change to keep stress down, btw.
I gave it a few pieces of mysis, which it actually ate. Which I took as a good sign until I came back an hour or so later to see food pellets spit out on the sand. Probably would never had noticed had the current not been turned down.....usually these would have been blown away.
So at this point I am going to keep a log of sorts, live or die, just to document for others. If you haven't caught the point, cover your power heads. I would go with no flow during maintenance over uncovered flow.
As I mentioned earlier, the last time this happened it caught the edge of the oral disk about 1/3 of the circumference and it was eating again within 48 hours. I did NOT intervene in the last incident, I simply took the gaurd off the pump and let the anemone pull itself out.
This time, I tried the same, but after an hour of no improvement I took the steps to cut the gaurd away from the anemone so it could then wind itself out. I thought about excising the tissue inside the gaurd that was pulled through into a ball of sorts with an exacto knife but bet against it.
It turns out it probably wouldn't have mattered. Unless the anemone is infected bacterially and rotting, it seems the recovery process includes sloughing off badly damaged tissue.....almost like shedding. One thing I noticed this morning is little pieces white tissue from the worst areas falling off the carpet. I think this is like what a human body does when burned.
So in general I would agree not to pull an anemone out of something it's caught in. Especially if it is pulled through but not abraided. If the tissue is intact leave it. Otherwise, I think you are good to cut off the bad tissue with a sharp blade (excepting for the tissue on the column/foot including the mouth because it doesn't look like anemones are designed to repair, rather replace (that's why the mouth has me doubly worried......). The ONLY saving grace here is that the foot is completely untouched so it is attached.
About 24 hours after the incident (day 2)
Still some eversion with the mouth.....can be seen in this shot.
Wish I took pics of the white tissue shedding, guess you guys will have to take my description.
Hope this is informative, someone will be here again some day (maybe even me, cripes).
Any input is always appreciated.
