Anemones not opening

[sin125gal]

Hey everyone
I'm looking for some help I'm new in the hobby about 7months in. I have a 125gal saltwater tank with a 20 gal sump. The problem I'm having is I have two carpet anemones one of them is big ( about 13in when open) and the 2nd one ( about 6in when open). The big one after about a month in the tank and being happy he's now not holding onto any and just blows around the tank. The 2nd one after being in the tank for about 5 months now won't open all the way and won't eat like before and is moving all over the tank. I'm not sure what info I would need to post for anyone to help so please just let me know and I'll post it. I just did a big water change I all so am having some more prob's but ill just start here. Thank everyone ahead of time for any help

Well starting is the first step. What we need to know to help.
1. Lighting - exact wattage and type of bulbs.
2. Water Parameters - ammonia, nitrite, nitrate, salinity, calcium, carbonate hardness, phisphates.
3, What has changed in the past year by date? New powerheads, new rock, animals, filter.
