i dont see the contradiction, you can do a quick acclimation and still reach the same salinity as whats in your tank, and when i said consistancy in salinity was key, i meant long term. im not claiming to be a starfish specialist, but am merely recounting what has worked for me. if credentials are an issue, im 11 credit hours away from having a BA and a BS in biology, and though my school doesnt offer marine biology specifically, i have taken every course offered that relates to marine bio. the real sensitivity in starfish lies in their kidneys, and if they stay in ammonia polluted shipping water too long, the kidneys will be damaged
