Somebody please help me...

I am not having luck with my green bubble tip anemones... One died while I was on vacation (and yes, a reefer was taking care of the tank while away) and now my 2nd (new) one seems to be "slipping away"...

I have checked all of my levels... All are almost unmeasurable... My salinity and temp are all good... All of my other inhabitants are very healthy... But my anemone just seems "weak"...

I know they are known to shrivel up sometimes, or even move around the tank until they are happy, but both have seemed to just shrivel up and die...

Any suggestions??? Thanks... DJ...
