I was a bit concerned at first the PBT and Black tang would not stop harassing him and I had to seperate the Tinker's with eggcrate. I took the egg crate away four days later and they still gave him hell but that has all but has subsided and the Tinker's has begun to fight back which is a good sign. Also getting him to eat was difficult, which was a suprise to me. I asked the collector who i got him from about what i should feed him and he gave me a gel based recipe that RCT and the Waikiki aquarium uses and voila he eats everything now. I just went to my local bays to collect ghost shrimp and pods and he loved that. Regards, Tim
