I finally stocked my tank last night with some fish, a green bulb-tipped anemone, and a xenia frag. I placed the anemone in the tank and several hours later when I went to bed, he had moved to a different part of the tank, I think by "jumping" into the current.

This morning I woke up and it was in two places, having split overnight. The pieces are on two different sides of LR.

Here's the photo from yesterday afternoon:

Here's the view from this morning. The red circle in the upper right is where it was yesterday afternoon. The arrow in the lower left is where it was last night when I went to sleep. You can see where the two pieces are now.

Since the piece on the left is close to the glass, I was able to get a close up photo:

The piece on the right is kind of wedged into some LR, so this was the best photo I could get:

Does anyone have any idea what happened?
Should I take one or both pieces out of the tank?
Should I just give up on it and take it back to the LFS and hope for a refund/exchange?

Thanks!

how long has the tank been up and running ?? what kind of lighting do you have ??

The tank's been up for 30 days. I've got three 65w Power Compact (dual tube) lights, split evenly between daylight and actinic.

i would suggest taking it back to the LFS. IMo, you do not have a mature enough tank yet for an anemone. i also do not think that PC lighting is strong enough to support and anemones requirements, but the opinions will vary on that.

Thanks for the quick and candid response!

What happened with the BTA?

Well, I ended up going back to the LFS and they ended up replacing the BTA with another one. I know Bobby recommended against the anemone, but I gave it one more try. Like a dumbass.

You can read the gory details on my member tank thread, but the cliff-note version is the new one ended up getting knocked behind my LR formation and I had to disassemble the tank to get it so the whole tank didn't get fouled up. All of the livestock ended up in a 10 gal tank with some LR since the DT was a sandy cloudy mess. The Anemone died in there.

I've decided to focus on reef-safe fish for now and maybe a few corals later.
