To answer your question, no. Just because the male doesn't make a nest doesn't mean he isn't interested. Some males will even build the bubblenest as they are spawning and putting the eggs in the nest.
To tell if the male is not interested in the female paired is mostly by not paying any attention to her. Like not flaring, swimming toward her, or even having no interest in chasing her are signs of the male or female being interested in their paired mate.

I don't want to let her out if he is not interested so I can try another male.
The male I am trying is more interested in me when I come into the room than he is her.
There is never "just" DT. DT has to be crossed with something. It's either long finned DT or short finned DT. And even then they were crossed with a tail type. DT is like a color.
