Ive lost 3 now...

[DainHanson]

After I moved my tank last August, my rbta got stressed and bleached out. Once I started to get it healthy again and it gained its color back it ended up splitting off and I ended up with 4. Two of them found spots and settled pretty quickly, another one was moving around quite a bit, and the fourth I found pretty quickly in my tunzee ph. Not long after that I found the third one in the same ph. I moved both tunzees off the back wall to the sides hoping that would help. About 2 months ago both my remaining rbtas stated moving all around the tank again. This morning, I found the original, my largest, was sucked into a ph. So I have one small one remaining and I do not want to lose it. Its currently on my back wall at the top of the tank.

What could be making them move all around my tank and not settle? I am assuming they are releasing their foot and getting sucked in and not moving into them which means they are stressed right? I have had rbtas in this tank for 3 or 4 years now with no problems so I don't know what's going on.

My params are:
Ammonia 0
Nitrates 0
Salinity 1.022
Temp 77-78
PH 8.2
Phosphates 0
Calcium 360 - 380
Alk 2.8
mag 1230

These are all the tests I take. Thanks

I would raise your SG up to 1.026, slowly.

What lights do you have?

Any recent changes to the tank?

4 96w PCs 2 10k 2 Actinics. Ill try raising my salintiy more with water changes, I do 5 gal weekly. I did recently move some rocks around but they were moving way before I did that. I have also been cleaning it a lot more trying to kick up detritus and remove it through pwc's and skimming. Is this what is stressing them?

What size tank?

While BTAs can be kept under PCs, if the tank is on the larger size, and the bulbs are old (( over 9 months )), that could be the reason that they are moving.

Its 80 gal. The 10ks were changed in Jan and the Actinics in Feb.

Would moving the pumps thus changing the water flow cause them to move around like this?

I would change out the actinics for 50/50s, would get more usable light that way.

Yes, one of the easiest ways to get any anemone to move is to change the flow in the tank.

Should I try to move the nem off the wall and back onto a rock or will that stress it out and more? I'm just worried I'm going to lose this one too and feel more comfortable on the wall. What should I do?
