Not meaning to gang up, but you get a 30 gallon tank, and throw in whatever you think looks nice or the pet store says is good without any research. Skimming through your old posts I see you had a horseshoe crab at one point, and argued over that a bit too. You also had a blue damsel and some other bi-color fish.
Research what you are going to be getting before
you get it!
You should just keep the two clowns and see if you can maintain those. One mistake, two mistakes, that's understandable, but you keep throwing random fish you find that you like into the tank with no research after people have told you not to.
Now for your anemones, they are living creatures. They eat, they get happy, they get upset, and they have requirements. Your lighting seems inadequate for your anemone.
Have a nice day.
