Ok, I have tried two different ywg’s with zero luck. The first one did great until I rearranged my rockwork and took away a lot of the caves and began swimming at the top of the tank and getting into the weir multiple times and I eventually rehomed him to a friend. So this made me think maybe it was just that one particular goby was angry so last week I bought another much smaller ywg. Wouldn’t you know he did the exact same thing so after finding him in my filter sock tonight I just put him in one of my evos. I am wanting more bottow dwellers and was hoping to be able to find a suitable goby that would work. If the yellows do this, would most likely any of the other watchmans act the same? Looking for suggestions for something fairly peaceful but won’t stir up my sand and cover my corals.
