that peat is good for fish tanks because ti makes the water softer ...

It may make the water softer but it depends what your water is to start with. If you have soft water and you make it softer you'll have issues, You'll also gain issues if you have hard water fish in soft water.

If the peat added is too much and forces the water to become very soft very fast the fish will most likely go into shock and die, depends how much peat there is.
