I just purchased a sleeper banded goby yesterday. He was an awesome fish and nice and fat. I acclimated him for close to an hour and then fresh water dipped him in RO. I then added him to my DT and he bolted somewhere to hide. He has not so much as poked his head out since and no trace of him at all. Usually any fish I've added come out before long but not this one. I am concerned that he went somewhere and died in the tank, got eaten by CUC, which doesn't take long at all. It has only been a day but could use a little feedback on this. My tank is a 65 gallon with a lot of hiding places in 80 lb's of live rock. He's a beautiful fish and pretty big in comparison to my existing small (under 3") fish. Thanks in advance for any and all feedback.
