Migrating Zoas

[gobytron]

Just wondering if anyone knows why...

I have a number of zoa frags in my tank, the lights are 2 x 55-65w CFL's.

I have noticed that a couple of them seem to want to move off of the frag disc and under some mushrooms, poking out from under the mushroom.

Why would they do this?

Too much light or flow?

Could be as easy as you may have aphasia near the disk, so the zoos are getting stung and moving away.

def a few aip in there....I'll have a closer look...don't see any close for now.

Frag plugs actually look spotless.

2 different frags doing this.
