To be honest, I had some crappy fish to start, but learned that I was wasting my time with them because they were just not even close to nice and I was spending just as much money as it takes to raise nice quality fish.
(((THESE AREN'T CRAPPY FISH TO START A LINE WITH!)))
So what I did was research and (REALLY READ) the betta territory site for form and finnage and leaned to get better fish from nice breeders here in the states. Also I did start with acceptable fish and got some really nice results.
The pair you have is wonderful and will produce pretty good fry. Start with them and PERFECT one line at a time. Remember rule of thumbs and take any advice or tips you can get on spawn methods.
I see you like HMPK over halfmoon. Correct me if I'm wrong. I prefer HMPK of course and don't like to work with HMs much. I've never had luck with them. Anyway my advice to you is to study the HMPK form and finnage and you will be set because you'll be able to evaluate the fish yourself instead of waiting for responses.
Unfortunately Karen Mac Auley only has HMs available, but I can guarantee that she won't disappoint because as much as I LOVE HMPKs, just seeing her pictures makes me want to get a pair of her HMs and spawn them. I refuse to get any others unless they are true quality.
Basically my point is... Take The chance and spawn this pair. Then work on perfecting it and line breed. Do your research (MORE IN DEPTH) about line breeding and HMPK form and finnage...you'll be all set!
I hope my little lecture has helped at all. Lol
