I doubt that he'll have any in stock since I don't think he gets them in anymore. Most of the ones seen in the U.S. come from breeders overseas and they are imported. I know of a guy in Chicago that has ones in stock right now that are probably what you are looking for. His name is Chris and re is very reputable. He is a sponsor on www.simplydiscus.com/forum
and he has nice stock. I believe most of them are between 1-1.25" and he's asking $160 each for them, which is reasonable IMO
considering that you really can't find them.
As far as breeding goes you want a 29g tank that has no substrate and you want LOTS of hiding caves and spaces, few plants, water with a temperature between 78-84, pH between 6.6-7.2, and a moderate hardness. You should have a powerhead or two in the tank simulating the flow of the rivers in which they are natively found. The flow should be about 8-10 times the volume of the tank per hour. Point the caves so that they are slightly facing the current because the males will use those caves to help raise the fry since the current will oxygenate and clean the eggs. Also, NO TANKMATES! Just the plecos. You will be able to keep a colony of 5-6 in a 29g tank but you need to have lots of hiding spaces and territories. Driftwood should also be added to the tank IMO
. Lighting shouldn't matter as long as you try to recreate the photoperiod of the day for them. I'd use the stock lighting that comes with the 29g tank for example 6-8 hours per day.
As far as your breeding group you are probably going to want to purchase 4-5 individuals at the same time. I was actually thinking about getting some from Chris but I just don't have the time right now to properly take care of them. Here is his website: Welcome to Windy City Discus!
The best way to get ahold of him is by calling him since he doesn't check emails that often.
