no prob with the above staying in here, its all welcome.
my thoughts with the freezer are different to some on here, people say ripping apart etc but are they not basing that on a human body? th temperature range a human can suvive is very wide , say 60 celcius swing.
tropical fish have a fairly narrow livable temperature range so to go from 26-28c /82 f to -20C / -4F in a few seconds would result in a very quick bodily shut down i would say.
of course brainal injury would be the quickest but thats a tad difficult with a neon unless you bash it with a meat hammer !
