Just wanted to share with you that probably the RT males are sterile. Maybe not all but being hybrids it is likely. I know of one guy who used a TX male and RT female and got some pretty decent babies out of them. The female was definitely fertile. My male has spawned with a Red Parrotfish but no babies from the cross. Been trying to find a female TX but the only one I had died. My next adventure is going to be trying to cross a Red Devil male to a TX female. I am not sure how they create the RT but I want to find out. They are amazing fish. Do you know of any U.S. people breeding and raising them? I don't.
