Waving hands

[naterade112886]

I had these waving hands for about 5 months
I bought a Large rock with dang near 100 of em... they since have shrunk significantly and some seem to be dying off.

This may sound like a silly question. But would small fluctuations in SG be the cause.
I mean like 1.024 to 1.022 or 1.023...

If you're speaking of Xenia, then it could be any number of issues from lighting to water chemistry. I doubt those subtle changes in SG would cause chronic die off. Of course consistency is better but any number of things can affect Xenia.

Hydroids perhaps? These things are VERY resilient... They all wave in the current, but are they pulsing? Addition by subtraction? Gorgonian?

I wouldn't call it a chronic die off. They are just alot smaller then when first added to the tank... my clown pair love them and play in them all the time so I just want to make sure I keep them healthy

I have Xenia that grow taller in some spots and stay short in others. They seem pretty good at adapting to flow/lighting situations. In some spots they pop up and then vanish.
