You do know Midas and red devil are almost indistinguishable these days it's hard to get a pure bred one. I'm actually selling mine now it's 16 inches my red devil MidasNo they're pretty much like a midas temperament and body shape wise. I did a quick search and a guy from this site had a 14" male so they get about the same size as well.
Exactly I know they're many pure breds Jeff rapps sells them as well. I'm not saying all Midas or Red Devils are but read the stickies has a lot of info of how authentic the species isNot at all. I can send an email right now and get a pure specimen of either. Same with a trimac or any other species including the xilo the op mentioned.
Midevils are hybrids and no different than a flowerhorn, red texas, blood parrot, etc. Which is fine, but lets call a spade a spade.
