I've been following your thread since the beginning and have a bit of advice to offer. I breed discus as well and I've learned a whole lot through the experience. The number one thing I've learned the hard way is about acquiring your stock. I've bought discus from many sources including discus hans and frank (the istore). What I've found is that buying small discus is a waste of money. I suspect the small 2" to 3" discus are more or less culls. They don't exhibit good traits as they grow. I've bought adult discus from hans that are super nice, and then bought several of the same varieties at the 2.5" size and as they grow up they don't compare to the adults I bought. Same with the istore discus from frank. About 1 out of ten are passable as potential breeding stock...if that. Most have pale color or terrible form and shape. You will save a whole lot of money buying high quality adults and proven pairs. If you buy a bunch of small discus you'll be stuck with a bunch of unsellable stock that you would never want to breed. Not to mention losses...you will lose several small discus as they grow out. This is inevitable. Larger discus are much hardier and someone else took the loses to grow them out. The old saying 'you get what you pay for' has never been more true when it comes to purchasing discus. Hope my experiences help you to not make the same mistakes I made in the beginning. Good luck man!
