It's so tempting to breed when you have great fish!
Good for you for giving them more time to mature... I have to wait for mine as well, they are just so little!
I was going to put another pair in the tank to occupy myself while waiting but I'm not sure yet. All my fish are conditioned, except my sorority which doesn't contain my breeders, so I could really pick out any of them. I'll see how I feel about that later on...
I would like to see how your feeding regimen works... I'm still adjusting mine and it seems to work much better.
Keep us updated with the HMPK, they are beautiful!
