You know I actually made a thread in the new to the hobby about whether or not people acclimate from one tank to the other - most people do and when I did my bleached yuma I did too because I know how fussy they are.. Then the other day when I changed a snail over I did it without thinking on my way to school and was like hmmm, wonder if that little guy will be okay, and why was I such an airhead?
Snail is fine.. i think something healthy could handle it if you keep your parameters near the same in both tanks.. Yeah there is other stuff we can't measure for but even with acclimation and transportation our corals still have to handle a bit of shock.
One of my concerns is going to ~6-10 inches or so of PC lighting into 18-20" or so of 4x54W T5s invididual reflectors and all.. they are *really* bright so I am weary of bleaching anything else out.
My fish knocked down a little acan frag I had that had some purple in it? I put it back up but one notch higher in its identical place in the aquarium- a few inches higher and the purple started going brown.. Moved it back down.. purple coming back. Go figure!
