Crimson is a hypomelanistic Miami Phase. Hypomelanistic means that it has reduced amount of melanin (black pigment) which makes it brighter and lighter in colour. Miami Phase is a local variety of normal corn (meaning this kind of corns can be found in the wild), and it has silvery grey background colour and dark red/brown saddles. Hypomelanistic added to Miami Phase causes light creamy or greyish background and red saddles. Crimsons - as they are selectively bred - act just like a Hypo if put together with any other morph that is not of miami phase background. For example Crimson + Ghost = Hypo het. Anery. So I'd suggest you pair you Crimson with other miami phase originated morph like Silver Queen.
If you pair your Crimson with your Anery you'd get all Normals het. Hypo, Anery (assuming they're not het. for eachother's traits).
If your snakes are opposite sex you shouldn't keep them in the same viv! They'll be sexually mature around the age of 1 or 2, and if they mate then, the female will surely be too small to lay eggs and she'll die.
