What is the effect of high gh low ph on fish and shrimp

[SeahSengYong]

High GH might be hard to molt for shrimps.
Low PH is good for most of the shrimps.

[Emokidz]

It really depends on the species of fish or shrimp you are talking about. In general, all shrimp prefer lower gh. pH requirements differ among species, especially so for fish.

[barmby]

Example: - the Australia rainbow fish will die living in low pH water.

However, a wild caught Apistogramma will generally require lower pH like 5 to 4.

it depends on what kind of fish.
