One has darker markings than the other one Dom, make sure you fix that issue before sending the first ten pairs out to the CSC beta test group.
If your mate bred blood shrimp that were afraid of the dark they wouldn't hide in caves where we don't get to see them most of the time. Also, electric blue markings would look better than just white and would make them sell like hotcakes - tell him biggles said ' you're welcome '.
