Hi everyone! I have a 5 gallon reef tank with just a pistol shrimp and a hi-fin red banded goby and was wondering if this behavior is abnormal. The goby always used to be out and swimming right outside the shrimp's burrow but in the past couple weeks he is never outside of the burrow and is always hiding - I can barely get him to come out to eat food. I was wondering what could have caused this behavior change and if there is anything I can do to help fix this...I would love to see my friend hanging out during the day again.
Thanks!
Thanks!
