JD's are probably among my favorite cichlids and these little guys (and gals) are absolutely adorable! You must be really happy with the way they're turning out, I know I would be.
How many generations are you expecting it to take before you get what you're looking for? Sorry if that's asked in a silly way, I'm not sure how to word my question in a way that it makes sense
I guess what I'm trying to ask is at what point do you say "I've done it! I've created a platinum JD!" and call it a day?
