My RBTA split last night (I believe it was due to stress, but not 100% certain) and the larger half immediately recovered and remained healthy looking. The other half looked very distressed and increasingly seems worse as of this morning. For context, I had turned of my pump in my tank (8 gallon AIO) to add copepods to my tank the night before and forgot to plug it back in, so my tank had zero flow for about 20 hours. Thanks be to God, everything else seems to be okay (soft corals and one stylo) as well as my clown and my pygmy hawkfish and various snails and halloween hermit.

My question is, is my bad looking anemone dying or just stressed? Should I remove it at this point to prevent water issues since my tank is so small or just let it be for now? Any advice and help is appreciated! Thank you.

This is a pic of it from last night:

This one is from this morning:

Stress can cause splits, recovery can seem perfect or painful, and sometimes a damaged nem will split to get rid of a damaged section.

Keep an eye on the weak section, it may be fine or it may be dying? I have seen nems travel through a power head that looked done that eventually recovered to live in many pieces of clones. Keep the tank running and clean and we shall see

Keep the thread updated as you go!

It’s very hard to tell, but this may or may not be why’s left of the anemone? I’m at work and my wife is sending me pics so it’s impossible to truly say but she can’t find it anywhere and it’s a very small tank so it likely could be. In a water volume of roughly 7 gallons (after rock and substrate displacement), is it going to crash my tank? Yesterday my nitrates were around 50 (likely the flow being off for 20 hours and a snail died) and so I did a 20ish% water change last night to account for that and put a fresh filter sock in. Not sure what nitrates are at now because my wife can’t test it for me.

That speck will not crash the tank. If it's pulled itself together then it has a high probability of a full recovery.
Okay, thanks for the info. My assumption was that it was already melting and that was all that was left, so I was thinking that may have already raised nitrates. Everything else in the tank including the other anemone seems fine otherwise.
