Help My BTA Anemone Looks REALLY bad

[Newbie Nano Reefer]

I’ve had this Anemone for around 3 weeks now in my 13.5 gallon tank with two occelliris clowns and ywg and pistol shrimp. When I first had it it looked better but this is the worst and it seems to be peeling from the mouth out. My parameters are as follows:
Ph is 8
Ammonia is 0
Nitrite 0
Nitrate is between 10-20
My tank is 4 months old

BTA are very resilience as long as you have good condition for them. Concentrate on keeping water conditions stable, temp and salinity too. Most should recover.

Do you know what’s wrong?

Update the Anemone is dead, woke up and it was upside down and defeated and bits were flaking off, I don’t know what the problem was but I’m going to wait a few months before getting a new one.

What about the rest of your parameters?
And what are you using to test parameters?

How is everything else in your tank doing?
