I killed one of Red Corals sea hares!

seahares do better when you drip aclimate but either way they are tough to ship

[reefwars]

cOulda been starving when you got it and to weak and stressed for acclimation or maybe it got harrassed by something in your tank I know my clans hate my sea hare goodluck

Next time I would drip acclimate 1.5-2 hours, inverts are often more sensitive to changes than fish. Better luck next time

Don't be embarassed, it's good you are coming on here for advice!

They are certainly a finicky species, I have never kept one longer than 2 months they just disappear one day.
