I want a female Enchanted Water Kelpari to breed with this male for the M3

My final goal is to have a male Enchanted Water Kelpari with Central Fins and Luminous Mane, and I already have a male and a female with Central Fins.

did you try the Advenced Search? there are severals females from that themme setted for breeding if you send a quick shearch for them, there is a good selection of trait witch is ideal if you are trying to start a project ^-^

Yep, I tried, and I had found one female that could breed, but even though I sent the owner a message they haven't replied back. This is my attempt at finding another one.

There is this girl that have it in hiden, with your boy it will give you around 75% chance to get a luminous mane visible

Or you could buy a female with no M3 and then add it with a mutator.

another way would be to cross breed to make yourself a female far enough in this guy's lineage to get a pair since you already have the trait. it take some time but cost little to nothing.

Thanks, I'll try breeding with her! I'm relatively new to breeding and the percentages still confuse me sometimes

This guide can help you understand breeding a bit better, it should help you with your breeding goal.
