I only temperature acclimate snails, corals, hermit crabs, and anemones. All fish and other inverts are drip acclimated. I used to drip corals and anemones. Mr. X indicated in a post he did temp only on corals and I saw a video of a reef at low tide where a lot if stuff was exposed to air for hours at a time which also convinced me. Saltwaterfish.com says to only temp acclimate anemones, and sometimes the water in the bag is so fouled anyway. I've gotten one long tentacle from them and just temp acclimated with good results. I've had zero losses with the stuff I temp acclimated.
