Thanks everybody.
All is not well with my anemone. It moved yesterday from front to back of the rock it is on now wedge between the rock and the "main reef". It is a small tank so there isn't much of a "main reef".
The optimistic part of me said that he is getting larger, eating, no longer bleached. The pessimistic side of me said his mouth looks bad, and he seem to be less rigid in term of holding his folds again the current and hugs the rock and sand more than he used to be a week ago. I was home and observed all day yesterday. I did not think that he is improving, rather, he seem to be moving backward health wise.
I cannot decide if his tentacles is getting longer so I must said that it is not. I keep the fish with him for about 4 days. Friday I saw that they put their face into his mouth so I removed them. They did not go all the way into him like I saw before like my previous fail attempt to get an Gigantea. Anyway, the tank is fish less at this time.
The tank have been established for more than 2 years but the whole last year was just there with light and top off water. It was full of macro-algae, pods some Xenia and some SPS. I only top off water, not significant feeding, no water change for at least 6 months. I clan up the whole thing. Do a 100% water change, take the rock out clean all the macro algae off, remove the damsel, vacuum the sand about 10 days before I put the anemone in. It is very stable and I have change 5 gallons every week since (out of 30 g tank). The SPS and Xenia I put in the tank grew like crazy. The Xenia is pulsing well and the clams are extending well and also growing in the month that I have them in this tank. Coraline algae is also start to grow with water changes and removal of the macro-algae. It is light by a 150 W double ended MH 10,000K. Right now circulation is by a single Vortech MP 10. Temperature is set at 83 degree and stable. It is cooled by fan when the light is on and I have a hang on CPR skimmer in the back. It produce some skimmates and is a place for the temp probe and for the heater.
I fed him every other day since got back from vacation 1 week ago. He is eating but seem to eat slower yesterday than he did before. As far as I know there were no additive or preservative added tot he shrimp. Human food but the shrimp probably not the freshest shrimp I have eaten. It does have some what of a strong shrimp smell. IME, fresh seafood have almost no odor to it. I think I will get some fish at the market and change his diet nest week. I will reduce the amount of food I feed him.
Here is a picture I just took. I thinks he looks a little better today than all day yesterday. The mouth, which cannot be seen easily, stills open. Overall, I am pessimistic at this point regarding how this anemone will do long term.
