It depend on if you want to eat the fish or just don't smell it!
Yes, religiously observant Jews can purchase fish from a store that sells non-kosher food. However, the fish in question must have its skin on. If it doesn't have its skin on, it must be in a sealed package that is labelled kosher by a reliable hechsher.
raw sliced what?if you're addressing meat,poultry,fish etc,then they should not be left outside fridge for 2 hours.they should be kept in a sealed or wrapped container in a fridge,at a temperature of 4-7 degree celcius.raw foods should be placed under cooked foods in a fridge to prevent cross contamination
There is no standard-size package for fish. It should weigh whatever is on the label.
put it in the fridge
no, this must be thrown away. five years of fish in a fridge is too long for fish. this is not eatable anymore.
I don't think it occurs in fish tanks because the sun isn't there. And also if its sealed then air can't go inside. So it is impossible!
it will be musty & moldy
wrap it up some how
If the pond is not deep, the fish can leave the pond. It is important to take good care of them or they will be tempted to leave.
i say either, better for safety from the fridge, make sure it is dry before battering.
