Cool goby! I have the same shrimp.
Hope your goby and blenny get on ... my bicolour chased my watchman and made it jump :(
Yeah I'm actually inlove with my shrimp..it's so nice, yellow with red markings..same as the wheeler goby. Narh it should be fine, the bi colour is slightly smaller and because they were introduced same time. Should be good.
At the moment. The bicolour is invading the left side rock work where the gramma resides..I'm watching..and the gramma is extending its mouth fully and extended its finds and swimming slept back and forth trying to scare the blenny..nek minut it takes no notice. Lol
The blennys actually resided at the base of my ric garden and left hand side rock work..my goby and shrimp have resided on the left side where my zoanthid garden is..so territory wise..they've all got their own little area. :)
