Okay, here are the details... Bought a cleaner shrimp yesterday at my LFS
. Healthy looking specimen. Active, bright colors, was actually cleaning some snails we also bought, etc. Brought it home and checked the LFS
water and found it at 1.019 SG
. Our tank is kept at just over 1.024. All the the other parameters were fine. Spent 3 hours drip acclimating the shrimp (snails and hermit crabs as well). Even though we spent 3 hours on the process, shrimp appeared to go into osmotic shock and was dead 2 hours after we added him to the tank. The only thing that went near him was the tang, she was super interested but never got close enough to touch him. I know that inverts are extremely sensitive to changes in water quality but does anyone have any ideas or tricks to spare these little buggers from now on? Everything else survived without incident. We have 2 or 3 other peppermint shrimp (sneaky little suckers) and a CBS as well and all of them molt regularly and seem to be thriving.
