Aquarium and Shabbat

The Daily Halacha Moment - Aquarium and Shabbat 🐠

״כל השונה הלכות בכל יום - מובטח לו שהוא בן ‎העולם הבא״ (נידה עג ע״א, מגילה כח:)

“Anyone who studies Halachot every day is guaranteed that he is destined for the world-to-come” (Megilla 28b, Niddah 73a)


May one change the water of an aquarium on Shabbat?


Interesting question, If one has a home aquarium, and the water needs to be changed on Shabbat then one may ask a non-Jew to take out the fish and change the water if it is a small aquarium and the fish are easily caught. A Jew, however, may not do so, since this would be considered Tzad. If the aquarium is large, then even a non-Jew may not take out the fish in order to change the water. [1] In such a case, or if one cannot find a non-Jew, then one can simply add some fresh water to the aquarium in order to maintain the fish from dying until after Shabbat. [2]
