My live rock is pretty high in some parts of my tank (within a few inches of the surface. When I do water changes some of it becomes exposed to the air. Does that matter? Should I try and move snails and hermit crabs off the top of the rocks so that they remain submerged? At this point I do not have any corals in my tank, when I do, do I need to make sure that they stay below the water line at all times or is it ok if they are exposed to air during a water change?

Thanks

it want hurt, though you might wanna get a cup and splash it or pour it over them if if its gonna take a while (over 30 min) to do a change. (when the tide goes out in the ocean, rocks are also exposed) REEF-ON!

I wouldn't worry about it, as long as you don't waste to much time getting the water refilled.

thanks for the replies...are there some types of corals that I should make sure do not have that kind of air exposure (even if it is just a couple of minutes) because they are either very sensitive to air or can't support their own weight outside of the water (maybe like finger leathers or something) effectively? I am goint to be adding a couple of corals this week and don't want to place them in spots that will be damagin to them in the long run.

Rock is fine out of the water.

The only thing that can't be exposed is sponges and gorgonians. Everything else (corals, rock, zoos are fine for 30-40 min)
