Bad News on my baby clownfish

Bad news.

I think I may have lost all 50 of my remaining babies (which were approaching 1 month old). My heater died last night and when I went to feed them this morning most were immobile on the bottom of the tank. 2 or 3 were swimming barely. And their color went from bright orange to a pale pink. Tank temp was around 70.

I got a new heater in there and fed them, but I think all is lost on this batch.

Will post an update tonight when I get home and check on them....
