Your tank is much too new to sustain 1 anemone, much less 3...What size is your tank, what was your method of cycling, & did you do a water change before adding any life in there? At 'less than a month' like your sig. says, I doubt if your tank is fully cycled & ready for any life yet. Clowns are quite hardy & can withstand wildly fluctuating chemistries in new tanks, but it's still inhumane to throw a bunch of sensitive animals in a newly cycling tank. & personally, I'd run far away from the LFS that said it was ok to put a carpet & 2 other anemones in a month old tank...
I agree w/ others about treating all those nems with cipro in a bucket until a QT is set up. I'd also do about a 40% water change & check your chemistries. If they're still whacked, maybe even re-home the clownfish & corals for awhile until you know for sure that your tank is truly cycled. You're in the right place for good, honest feedback in this amazing hobby; just ask questions here BEFORE making impulsive purchases. btw, are those 4 clowns in 2nd pic? If so, you're going to run into trouble w/ all of those in 1 tank...Keep 1 pair per tank. Good luck & welcome to Reef Central!
