I had an orange stripe prawn goby and I was going to get him a pistol shrimp the next day but he jumped out of the tank because I have t5s and no lid.... But a beautiful fish just make sure you have a lid.
I have both and the one i linked, is very very pretty and depending on their mood changes colors and can get much darker with blue and bright red speckles all over.
If you have all LR and substrate you already have enough bacteria for filtration but to be safe I would wait few more days. There might be some spikes in between.
