Just so you are aware, 5 months isn't really old enough to be sure of a crested gecko's age. Males can 'bloom' as old as 9 months so I would not assume your three geckos are female till they are nine months old or older.

As for what would be good to breed them with...I can't really say. The 'hot' morph seems to change regularly. Go with what you want to work with, or aim for a particular pattern/color combination you prefer.
