We had a 12 hour power loss, the house temp got down to about 61 degrees.
When the power came back both my clowns were very slugish, but active,
unbtil one got suckedagainst the protein skimmer(cpr backpack), as soon as
it happened i shut it off. but it looks like the damage was done. Is ther
any hope for these guys to come back?

During the outage i was able to heat some water up in my outdoor grille, put
the water in plastic juice bottles, and float them in the tank to keep the
temp somewhat higher than the temp in the house.
