What's the pH and hardness at? I never got any breeding behavior with mine, but I kept them in our tap water which here is about 6.7 pH and pretty soft. I never got them into their own tank where I could do up a proper blackwater tank like yours. Still darn impressive, they are the hardest dwarves to bred water wise.
My tap water is also pretty soft. PH at 7.2 KH 2 GH 3 The ph in the tank is at 5.5. There is no hardness. I'm lucky enough to have a lot of oak trees in my backyard. All the wood except one piece in the tank, came from my backyard. I put DI water into a 55 gallon drum. In the drum I have a large piece of oak, oak leaves and a bag of peat moss. The water ages for a few days. That's the water I use. In addition to the oak in the tank , there are oak leaves and peat moss in the filter.
I fed them very well. Lots of bloodworms, Mysis shrimp, freeze dried krill and some live guppies. They wont eat pellets or flakes. Hopefully I'll get them to eat them soon.
