I doubt it was a fish tank thermometer only, it was probably a fish tank controller that had a thermometer as one of it's functions. On something like a saltwater tank where you might have thousands of dollars in corals and such the controller is used to regulate temperature, chemicals and so on. One tiny slip up in parameters and thousands of dollars are down the drain. IOT for that sort of things makes total sense.
Network isolated and all that for sure though.
On the other hand if the casino's security were properly setup even an IOT device wouldn't be a concern as it would have required at least two weaknesses to got to this point. In my opinion you have to treat an internal network as if it was public anyhow.
