Is it bleached? Do you have a picture you can post? Ive had anemones split it in the past, some were overnight some took a week or so. It was large and seemed like it couldn't quite get a far enough stretch to split.
There was a time about 5 day ago that it almost looked like it was splitting then it came back together in this C shape, you can see the gap where the mouth is supposed to be..... He doesn't seem to be dying
What kind of light and how many watts is this under?
That is a very bleached out. I don't think I would even try spot feeding as it might be too much for it.
If spot feeding go with small stuff like thawed mysis shrimp. This young man does a good job explaining the reason and fix.
Anyone can make cool video on youtube. The internet is filled with... you know what.
Anemone can take very high light and you can find bubble tips anemone in shallow tidal pools that blasted over a thousand PAR under the sun.
15.6% change every week or two,.... nO later than 2 weeks, No skimmer. no carbon reactor i am hanging chemipurer elite in first chamber and running activated carbon filter in second with small amount of filter floss below thats it, I have 2 OC clowns, 1 shrimp goby, two clown gobys. So i don't think i am over bio load.....especially changing water so frequently.
yes stock i turned rock he was on to face light and fed him tiny bits of krill seems to be doing a little better filling out more etc.... though it looks like it tried to split and has two mouths, but is still together at a point.
