Steps to Take for a Broken Fish Tank

If your fish tank breaks, it can be a stressful situation for both you and your fish. However, there are steps you can take to ensure the safety and well-being of your aquatic friends. Here is a guide on what to do if your fish tank breaks:

Get your fish into conditioned water

The first and most important priority is to transfer your fish into conditioned water as quickly as possible. This will help minimize any shock they may experience due to the sudden change in environment. If you have spare aquarium water available, use that. Otherwise, prepare fresh dechlorinated water with the appropriate temperature and pH levels for your fish.
