Well I can’t see the video but I do have some thoughts.
If I go down to the mall and choose out a beautiful couple from the folks available I don’t know if my selection would suit either of them for mates.
With that in mind, you have to consider that the two fish are not mature and the battle is to decide who gets to be the daddy. This is much more difficult to arrange than our hypothetical scenario at the mall!
Further more, you have selected two morphs that may not speak the same language and may not recognize each others mating dance cues. They may fight to the death waiting to see the other one submit to the arrangement.
I just remembered that next Tuesday is our anniversary here at home. Thanks for saving me from another beating.
Good luck!
