It's a fishless tank minus the yellow watchman FYI. Does this change anything? Can I treat with him in tank? Could this spread to inverts?
It means that if the goby's out of the tank, any disease that can't survive without a fish host can't survive long in the tank.
Whatever he's got going on, it's _unlikely_ to spread to the inverts. Most diseases affect either fish or inverts - not both.
