Ok but many LFS have ich, marine velvet and brook in their tanks, so is a LFS a reference?

Does liveaquaria do the same with anemone?

I think if it is just a coral (or nem) then the risk of adding a parasite is low. Corals and nems slime up, expand and contract and would make it hard for any parasite to stick there for any length of time. The risk gets greater when the coral or nem is on a rock....the bigger the rock, the greater the surface area for potential problems

that make sense. I was more afraid that some free swimming parasite could have been in the water with the anemone though, but I guess the risk is very low and only the water that was stick to the anemone got into the tank.

On a side note ...
Are you able to run that 4 x 24 in pairs? One pair to start, then the second for mid-day?
Only reason I ask is it seems a lot for the clowns in a QT if all they get is darkness, and then BAM 96 watts, especially of T5HO.
I have a 15w T8 for my 20 that I'll use for fish, and a 65w PC for light dependant dudes.

There is an anemone in there so that one need a lot of light.

The clownfish don't mind the light at all either.

I start actinic + fiji purple first, then the aquablue special kick in for about 6 hours.

The anemone would probably not survive under PC.

update
 

Well, I had to move the anemone to my main tank already because it was dying. It was so shriveled that I thought it would die that same day. The tentacles were flat and empty, with no substance. It was going worse each day.

I am not sure if it is the T5HO light, or the clownfish hosting already that bothered the anemone but it was going to die.

After a day alone in the main tank, no host and good Pheonix 14K MH plus a bit of natural sunlight (one hour), the anemone has made an incredible come back. It is now beautifull and full.

I just hope that there was no disease with it. Again I took it out in my hand to put it in the tank so very little of the water got into my tank. I had no choice, either lose the anemone or take the risk and put it in the main tank.

I had the anemone with the clownfish in quarantine for 2 weeks now. I wish I could have keep it at least another week in quarantine.
