We present the smoothed-particle hydrodynamics simulation code, Bonsai-SPH, which is a continuation of our previously developed gravity-only hierarchical $N$-body code (called Bonsai). The code is optimized for Graphics Processing Unit (GPU) accelerators which enables researchers to take advantage of these powerful computational resources. Bonsa-SPH produces simulation results comparable with state-of-the-art, CPU based, codes, but using an order of magnitude less computation time. The code is freely available online and the details are described in this work.

List of changes
* Expanded upon differences/advantages/disadvantages between SPH and Grid codes
* Added a paragraph about moving grid codes that combine advantages of SPH and grid codes into a single method.
* Expanded upon the problems faced
* Explain in further detail the performance difference between the multi-GPU gravity and multi-GPU SPH methods and which steps have to be taken to optimize the SPH method.
