Is it mean that this pump is bad Question

    I saw this brown patches look like been burnt near the pump. The pump itself is still working. Does this mean the pump is bad? I don't know whether it's pumping hot air.

    You mean an air pump right? Check for warping or any deformity. Check if there are any cracks or if the plastic is brittle. When in operation check if it's very hot. The fish will be fine. The bigger concern is that if it will cause a fire.
