I killed one of Red Corals sea hares!
 

No Idea how I did it :redface:

I did a 10% WC before I went to get it.

Brought the thing home and acclimated it for about 45 mins.

I floated the bag for around 20 mins and then started to add small amounts of tank water.

I checked all my water parameters and everything checked out perfect. My KH and CA are a bit low. Salinity a bit on the low side at 1.024.

Does anybody have any ideas what I might have done or what happened?? I feel pretty bad and definitely embarrassed lol

aclimation
 

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

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.
