Yeah, they can breed though I am pretty sure thats how you get a red texas. I think you can get texas to breed with a lot of fish.
Do what davey said if you really wanna be safe, buy eggcrate diffuser at a hardware store it should be by the flourescent light section and cut it to fit your tank and stick that in there. Make sure you put it in before you put the fish in to make sure your midas cant knock it over or something.
I would also say to try and get a decent sized female since its going to be intruding on the already established midas territory.
good luck, tell us what fish you decide to cross it with.
