Healthy Sebae Anemones:
Now, bringing a sebae back to health can be done, but it is not easy. At least 80% of the time the anemone is going to die because the owner doesn't have the right equipment or system to do it.
When I purchased my sebae back on June 30th, 2010 It was in extremely rough shape. It was the size of a toonie or silver dollar. White with purple tips and the tentacles were pulling in on themselves.
I placed it in my tank, a 58g on a rock about 8-9 inches from the surface of the water to allow it to get as much lights as possible. My lighting is a 6x39w Tek T5 unit.
It took more than 48 hours for it to adhere itsself to my rock work.
I fed the anemone every other day at first and when the color started coming back I backed it off a little bit.
As of Oct 27th, 2010 the anemone is twice the size it was and half of it's color has returned. It still has a lot of healing to go.
This is why we are saying you do not have the right set up to keep this anemone healthy and the fact it has let go and flipped over is an indication of this.
I would suggest that you get either a 2-4 bulb t5 unit with individual reflectors. The later one better one. Or, a par38 led bulb to give this anemone the light it needs.
Additionally, you will need to feed this anemone meaty foods every other day for a good month.
Because you will need to feed this anemone so often, you will also need to have a skimmer on this tank to keep it as clean as possible, or do daily water changes.
Once this anemone starts growing, it can grow fast and can get up to and over 20 inches in size.
I hope this information helps you.
