I've been distracted with my pond, a new koi not doing well, and the many babies Greenie and Oliver have had. But I'm finally updating again.
I had to divide the tank for a while. Greenie was being brutal to Oliver. She nipped off his trailers

I was very upset. She was pissed when I separated them. She sat staring through the divider glaring at him and flashing her stripes.
Mad Greenie.
They would still be divided, but Oliver jumped the divider somehow and was over on her side after a couple weeks. So I just took it out. Since then he has held his ground. I think that gave him the boost he needed. There hasn't been any major damage since then. Just some lip locking a couple times.
He has been bulking up more now. I think he is around 5 1/2, not 6" yet for sure since Greenie is still just a hair longer then him. If I was brave I'd take them out to measure, but I'm so scared I'll hurt or traumatize them.
And finally, here is Oliver

His tail is finally getting a thicker orange band. I've also noticed that his tail is smaller then most gt I've seen.
