50/50 mix I have had these results with these goby's, I had a white ray yasha haze goby pair up with a yellow watchman for 18 months then I no longer had a white ray yasha haze goby. If i was in your shoes i would trade your blackray shrimp goby and get another white ray yasha haze goby and add it just after the lights go out you will have a 50/50 chance of them pairing up and then you will be sitting real well!!!
hey jeff, you seem to know a lot about the pistol shrimp and gobys. let me ask you this. so i found a goby i like but this place never got them in and i needed a goby for my shrimp. i have a candycane pistol shrimp about 1.5 inches long and a white ray yasha haze goby same size in a 40 gallon breeder with roughly 65lbs of rock. i found a blackray shrimp goby also. if i put him in the tank will he fight with my white ray or will both gobys pair with the shrimp and everything be all goody goody?
