Has anyone put a violet dragon gobi in a goldfish tank?

I'm interested in getting a dragon gobi but not sure if one would be a good fit for my current aquarium setups. I have a large freshwater tank primarily with medium to large goldfish as well as a freshwater tank with various small mollies and catfish. I have read that the gobi is actually from brackish water and is generally a very gentle fish with the exception of eating small sick/injured fish. I also learned that they require warmer water and due to relative blindness, eat primarily at night and cannot compete for food. However I have read a few accounts of aquarium owners pairing them with goldfish. I'm wondering if anyone has any insight or experience with the dragon gobi. I'd love to have one, but obviously want to ensure that I have the proper setup for such a fish. Thanks.
