I read recently that when acclimating fish and inverts at the same time, it's important that you never mix the water from the fish bags with the water from the invert bags. You're always supposed to acclimate them seperately. i realize that hermit crabs need more time to get used to temp. changes....is that the only reason?? Just curious as to if anybody knew exactly why.
Hmm...I've never heard this. Many inverts DO require a slower acclimation. However if you're acclimating correctly with a drip line, it's fine for both inverts and fish. Inverts like starfish, and anemones really shouldn't be exposed to air, which fish, crabs, snails will tolerate fine as long as it's quick, but I try not to expose them either just because it's an added stress.
I CAN think of a reason not to acclimate them together, but it isn't due to the fish/inverts native requirements it has to do with how some LFS operate. Some LFS preventatively treat their fish-only systems with medications that contain copper to keep ich and other parsites down.
If you ever go in a LFS and they seem to have all their fish in one bank of tanks, and there aren't any inverts or corals in with them, they may be doing this. If so, I'd then acclimate them in seperate buckets. (I actually use several dollar store plastic pitchers for acclimation.)
If on the other hand you're in the store and they have fish and corals/inverts in the same tanks, then I wouldn't worry about it, and just acclimate them together.
