Question:
An act that occurred on Saturday – a child who slipped in the living room and encountered an aquarium of fish and the glass of the aquarium cracked, and approximately within fifteen minutes the water in the aquarium is drained, is it possible to move the fish in the aquarium to another place full of water and save them before they die, because there are supposedly three problems here – borer, muktzeh, and hunting?
Answer:
It is possible to remove by a mug from the aquarium and transferred elsewhere – to a bathtub full of water, before the fish dies, and there is no ‘borer’ in it, because there is no prohibition of borer when a dry and wet are together, and also rejected the problem of muktzeh because of ‘tzar balai chaim’, and since the fish are in the aquarium are hunted and standing there, therefor you can transefer elsewhere.
