I have 3 albino auratus. When they were small they were all yellow with white stripes. When they got older one of them lost the yellow color and turned mainly all white. I believe it is male and yours probably is too.
I also had 3 normal auratus. As they got bigger 2 of them started getting darker (male color) and one was beating the other up bad (he even bit off it's tail). I put the tailess one in another tank until it grew back then took him back to the LFS. He never did get as dark colored as the real mean male so I'm thinking it was a subdom male and the real mean one a dominate male. The one I thought was the female is now getting a little darker color on "her?" too. She's still colored the same but her face is getting dirty looking and a little on her belly. I'm wondering if she is a he too or if females do get a little dark on them as they get older. So far there isn't any trouble between the 2 I have left and if she really is a she I might keep the 2 and try to get a couple more females.
I can't say for sure but I really don't think the albino and the normal auratus will breed with each other if there is enough females of each. I've never seen mine paying much attention to each other. I was more worried about my albino socolofi females getting with the male albino auratus because he looks so much like them.
Sorry this is so long and not really much help lol. I haven't had any fry from any of the auratus yet for sure. I had one of the albinos holding one time but she swallowed or something after about a week. I have 2 tiny fry right now that may be normal auratus or maingano. I didn't notice any fish holding. They aren't albino but they have a horizontal stripe. I think they are starting to look a little blue so I'm leaning toward them being maingano but this is my first fry so I can't say 100%. I guess since I didn't witness the spawn I can't say 100% about anything about them other than they are fish lol.
Good luck with your fish and if you do have the the auratus cross breed, let us know how it turns out. Again, sorry so long lol.
