The way to start if I were you is to dump that super pastel male and put your money towards a decent female and start plumping her up. It will take you a few years- unless you can afford a good sized adult/sub-adult girl.

Start collecting females. They take longer to get to breeding size (2-3 years). You can wait a year or two on males. In that time your desired male prices will drop. Why feed a higher priced male for 2 years while you fatten up your females when you can get him cheaper in a year and feed him less?

A breeder once told me this- buy some desirable females to breed for what you want. Take the lesser common denominator on your female. Here is my personal example... I want to breed Nuclear Spiders. Well... that takes a Fire/Butter/Spider. A Spider girl is the cheapest of them all, so I got a few. Then he said- never breed a lesser quality male to any female. My next purchase was a FireButter male. Next year they will all be ready to breed if all goes well. I bought sub-adult/adult females and a young male, so I will only feed each for a year before they hopefully breed.

and.... one the Fires- you really may want to consider your stance on those. They clean up anything. Here's my 0.1 FireFly and my 1.0 FireButter. Not cheap, but amazing quality.
