As you can see the material I used in the tank reflects the surrounding objects,but I want it to show the reflection a litle bit and shine
there is my shaing properties what should ı do
You can use the Light Path node, it has plenty sockets that filter the type of rays. Though I think it works only on Cycles. One of them being "Is Reflection Ray", which filters out anything that is a reflection.
Use that node's "Is Reflection Ray", and use it as a factor of a Mix Shader node. In that mix node, plug your glass shader in the first shader slot, and whatever reflection-less shader in the second shader slot.
