Can i help my BTA

[Kmst80]

A little Backround, Tank has been running for 9 months, bta has been in the tank for 8 months.
She was fine until about a month ago when the tentacles on one side started shriveling and curling and after another couple of weeks the whole anemone has short shriveled up tentacles.
She closes up for long periods and then opens up again with short tentacles, mouth is mostly closed, sometimes somewhat open.
I don't know if this is a bacterial infection or other other. Her foot is still firmly attached to the rock, in the backround are 4 forest fire bta"s that are all doing fine.

Parameters:

Nitrate 20ppm
Phos 0.57 ppm
Alk 8
Calcium 430 ppm
Mag 1400

About 2 weeks ago i realizedd i didn't read colors for nitrate/phosphate right, bought hanna checkers and Nitrate was 59ppm and Phosphate 1.26ppm.
Did a few 20 % waterchanges a few days in a row and finally slowly getting both under control. The BTA showed the short tentacles before i did the waterchanges already.

My question is, what can i do to help her? I am in australia so i can't get Cipro without prescription, atm. i am focusing on getting the water clean and stable and feeding the Bta twice a week to help her( when she was fine i never fed her).

First pic is from a month ago,(its the one top of rock with long tentacles), second is from today

I think you’re on the right track, work on getting the nitrates to a range of 5-10 ppm and the phosphates down to 0.03-0.1. Maybe hold off on feedings. The process of feeding can be a stressor on its own, requiring a lot of energy expenditure to break down and absorb the food. You appear to have proper lighting, which should be a sufficient food source. The nitrates and phosphates in the ranges above will also help to feed the zooxanthellae.

Maybe try reaching out to a veterinary clinic and explain your situation and see if they would be willing to sell you some ciprofloxacin.

@Eagle_Steve @Lost in the Sauce might have some more advice.

Nitrates and Phosphates used to be in that range until I raised phyto dosing. That's exactly where I want them again.

Your nitrates and phosphates are not the issue. BTAs will thrive in much higher levels of both. Nitrates are a food source for them.
My suspicion is chemical warfare from the 4 forest fire anemones. I have had some combinations of Bubble Tip anemones do exactly this. More likely to be a problem in a smaller tank but it can still be a problem in a 300 gallon tank. I added a rainbow to my 300 with a bunch of well established Rose BTAs and green and purple BTAs. I had probably 24 total, most 6-14” across. As the rainbow grew the others started to shrink in size and numbers especially the green and purple ones. To the point I no longer have any green and purple BTAs and just a few roses.
