Collateral damage

Last month I was peering into the back of the tank and spotted an odd looking tentacle waving around. I stared a bit closer and discovered a fully grown Aiptasia anemone happily growing back there, argh!! Where did it come from? How long had it been there?? I have absolutely no idea, lol! I could only find the one which in itself appears to be a minor miracle. It was well hidden behind the sun coral from one side and large bushy gorgonian from the other. It was pure luck that I discovered it at all to be honest

Even though it seemed to minding its own business and not harming anything I decided it needed to be dealt with. Out came the Aiptasia RX and I gave it a good dosing. The next day I realised my mistake, the Plexaurella gorgonian that's sited on the rock below looked really rough. All the polyps had retracted and they stayed retracted. Clearly it must have taken an accidental hit from the Aiptasia treatment.  For five days it showed no life whatsoever and then on sixth day a 4cm section of the uppermost branch just melted away exposing the stalk underneath. I feared the worst but on day seven some of the polyps on the lower branches started to extend once more and over the next week it gradually returned to normal. Eighteen days post treatment it looked good as new, the entire section of branch that had stripped had been covered over again. Amazing!

Oh and by the way there's no sign of the Aiptasia (for now).
