Questions on BTA

[RicGio]

:worried:I added a mated pair of True Percula clowns that are hosting in a BTA. The anemone is acting oddly.

I put it in a bottom corner of the tank where it gets fairly low lighting. 90 gal with 2 MARS aqua "Chinese LED black boxes" set at 30% blue and 12% white Max with a photo period of 8 hours.

The anemone attached well and opens up to a nice full spread when the lights are off. BUT when the light comes on it will slooooowly shrink down to 1/3 its extended size. When the lights go off it is back to full size within an hour.

Is it getting too much light? I thought these things liked a lot of light?

When did you get your nems? If recent then maybe they are adjusting to your light intensity. Mine close up after light goes off and open when light is on.

Had it about a week.

That's still recent. Give them sometime.

As long as they stay attached, mouth closed and colored well, nothing really to worry about.

Cheers!

Lower white to 5% and blue to 25%. After a week bump up the blue if other corals need it. I'm using Chinese blackbox as well. My white has always been at 1%

Lowest I can go on my lights is 10%. Controlling them with an apex VDM. I rigged a “visor” to block some of the light and it looks a bit better today.

The anemone needs to be bigger than the clowns and adjust first. I made the same mistake. First introduce the nem and once it is acclimated and has settled add the clowns. Now all you can do is wait and monitor the situation. If the nem seems stressed separate the clowns from the nem.
