How do you turn a mouse tank into a fish tank?

Answer 1

If it's a fish tank that has previously been used for keeping mice, then all you need to do is rinse it out thoroughly with hot water (don't use cleaning agents) and then set up a filter and heater, just as for any other fish tank - there are loads of websites that explain how to set up an aquarium. Don't forget to cycle your tank before you add fish!

If you bought the tank as a mouse tank, I strongly recommend against trying to keep fish in it. This is because a mouse tank was never intended to hold water, and the quality of the glass and the seals just won't be adequate for the weight and pressure when it's full of water. It may not be watertight, and even if it is, you have a very good chance of coming home to find that either the sealant or the glass itself has failed and there's water all over the floor. In addition, the sealant used may be liquid nails or similar, which will leach toxic chemicals into the water and kill the fish.
