An anemone inflating and deflating is perfectly normal. An anemone such as this in a system your size likely isn't going to do well in the long term, though.
I have to tell you that it's incredibly disheartening to try to help someone who won't listen to a single thing posted. I honestly don't think anyone can help you at this point. I've told you that you're grossly overstocked. I've told you that you're going
way too quickly in your stocking. I've told you that you have animals that are not at all well-suited to your system, all to no avail.
Let's look at your current list:
29G REEF
maroon clown
pearly jawfish
purple headed wrasse (pariotfish)
one blue chromes
cleaner shrimp
Singapore angel
35lb of LR
9 corals
one feather duster
5 blue legged hermits.
It pains me to think that you're buying fish so enthusiastically, but not taking care to research first so as to avoid continuing to kill animals.
You're keeping the Singapore angel it appears, even though I and others have told you that it's going to soon outgrow this tank. You're keeping the maroon, even though I and others have told you that it
will become aggressive towards the other fish in your tank. You've got a jawfish of a type that should only be kept by advanced aquarists, and a number of hermit crabs that your system will be hard-pressed to support. If you're now calling your "purple headed wrasse" a parrotfish, it's even more painful knowing that you have what I can only assume are stony corals in this
29 gallon system.
You are using brine shrimp, an incredibly deficit food source, as a staple, intermixed with lesser amounts of more appropriate foodstuffs. Brine shrimp is about as good for the fish to live on as pot
ato chips are for us to live on. And no fish in your system feeds on one specific food in nature ever, they must have a variety. Your system is so new, there's no way it can be stable and producing the micro-organisms that animals like the feather duster and jawfish should like to feed on. That means that it's up to you to provide this variety. I can't emphasize strongly enough that your system really needs to be stable and well-established before you add specimens like anemones and jawfishes.
PLEASE don't mix anemones with sessile invertebrates (animals that
can't move)! Please stop putting anything into this tank until you've A: made some important changes in the stock load, and B: waited for the system to stabilize! PLEASE start researching FIRST, instead of waiting until a creature is on its way out to post that you're having trouble! We're here to
help, and you are not letting us do that.
