Hi everyone so I have had this tank for about three months and everything had been fine till about 2 weeks ago when I added an anemone I have been doing water changes every 1-2 weeks some of the anemone legs have been kind of shriveled up and I’m not sure what is the problem they are not completely shriveled up just some of them and the ones that have shriveled up are kind of greenish. Please help wouldn’t let me post a picture
