Guys, I have found out that I have the Randalli Pistol in my tank. He is pretty young and quite small. I wasn’t aware he was in there, I thought he was at first then all went silent in tank. Now I have added a tiger and symbo goby pair, low and behold first night they are in and I spot that I actually do have a hitchhiker. Don’t want it to die by the hands of the tiger so if there is anyone out there who would be willing to take it let me know. I’m hoping he stays out of the way for now or at least until I can catch him.
