My nem expertise... because it's the only thing I have ever been successful with...
Well...adjust flow and light normally and nem will find its spot. If you keep changing parameters, your anemone will move all the time. Also, anemone can look funky for a few days and back looking healthy. Don;'t force feed, specially large chunks. You can target feed with mysis or brine close to it and it should stick to its tentacles.
Dont go overboard with perfect water chem, mine have always done fine with some phosphate and nitrates (0.25-0.5/25/50)
I agree with everyone, if the anemone is creeping up, probably not enough light. Maybe you can find an affordable LED fixture on amazon. Dont blast the anemone too fast though “
I added one bulb to my fixture for 2 days before adding the next to try and slowly ramp it in. He is no longer moving up but has moved back down. He just looks like crap tbh, also I am done trying to feed it for a few weeks as I was advised they really don’t need to eat as often as thought. Some days he looks like he is starting to melt and the foothold releases a little bit. Then I wake up and he is firm again And has a good grasp. Just seems like he is holding on to the last bit of life he has and still hoping for a turn around I also understand there is a huge difference between fresh and salt not to bring this into the mix by saying I’m an expert... but I have never had any issues with ammonia in my ten years of freshwater keeping. I have had salt off and on. In the past I have had some sps corals I received on live rock from a guy I made a few trades with and every coral I got with the rocks thrived until an unforgettable power outage where my fish room dropped to 40 degrees and I had no back up generator to even try and save my fish room at all. Ended up loosing well over 1000 gallons and hundreds and hundreds of my tropical fish I would breed. The problem i am having is maybe I should have just let this guy die as crappy as that sounds because the stress of trying to bring him back from his zombie form is quite irking Because it seems a lot of people have a lot of different methods and options on what he needs. It is quite boggling how these animals live and move but I feel the need to try and help him due to me need to try and help sick and injured animals.
