On Sunday, 12/24, afternoon I set up a quarantine tank using a storage tote, heater, and an air pump with two air stones running. No light initially. I matched the salinity and temperature of my stored saltwater and QT to my display tank before moving the anemone. Around 2:00 PM I moved the anemone and administered 250 mg of cipro / 10 gallons of QT water. The anemone was placed on a ceramic dinner plate in QT. It moved itself to extend its foot out sideways and kind of folded itself like a taco. It righted itself and opened up normally, moving around a bit through the day. It's mouth was still wide open.
Around 10:00 PM that night I went to check on it before going to bed. The water was quite cloudy. I used a turkey baster to gently blow some detritus off of it's mouth and found that the interior of the anemone seemed to be deteriorating and coming off in strips. It seemed this was the end. I performed a 100% water change because of the cloudiness and amount of debris in the water. I smelled the anemone when it was out of water and it did not smell.
The next morning, Monday 12/25, the deterioration had continued. I placed a light over the tank on low power. The anemone shrunk up a little and closed its mouth a little. I think it was still alive at that point. I let things go until around 2:00 PM when the water was too cloudy to see clearly and I did a 100% water change and redosed cipro. The anemone smelled pretty bad. At this point I was 99% sure it was gone, but filled the tank back up one last time anyway.
Last night around 6:00 PM, the anemone was clearly gone. It looked like a pile of ground hamburger protruding from it's mouth. I drained the tank one last time before disposing of the anemone in a plastic bag. Like others have mentioned, there was a very putrid smell.
I'm feeling pretty terrible over the whole deal.
I think my last chance to really save the anemone came last Wednesday when I got my cipro. For a lot of reasons I decided to follow the low dose 0.125 mg / L in the display tank protocol. Looking back, I shouldn't have done that. I should have gone into QT at that point and administered at 250 mg / 10 gallons.
Leaving the weakened anemone in with the clowns was also a mistake. After that first big deflate when the clowns kept trying to feed it that shell I could've pulled it even without cipro on hand, but just to get it away from them.
I think
@dieselkeeper was ultimately right here. I think that in my inexperience I took deflations for granted and assumed that they were part of an anemones process in adjusting / healing. I think they are more significant than I gave them credit for.
In a few months, when I am moved past this mentally and emotionally and am ready to try again, I think I will go right into QT upon delivery (with a proper 20 gallon setup). I'll do 250 mg / 10 gallons of cipro for 5-7 days. I will move the clownfish out of the display tank and let the anemone get settled for 7-14 days. When I'm comfortable that it is settled in and passing health checks mentioned by other users on this forum, then I'll reintroduce the clownfish to the display tank.
Please let me know if you guys have any other thoughts / advice on what I did or on my future plans. I'm really trying to learn here. It sucks that this learning experience went the hard way. I have to do better for my pet next time.
Thanks, Jacob
