Also if you are ever down here in Vancouver, a local member makes a killer beef heart mixture that we buy from! My discus go berserk for it! I'm sure I can also find a way to freeze it and send it to you too since you are so close! Just let me know and i can get a order in for you before you come down! Anyways here is the ingredients he uses:
The main ingredients I use are Free Range Organic beef heart (no hormones, no antibiotics, grass\alfala feed, remove all fat and membrane), Shrimp (shell removed), Wild salmon (skin and bones removed) and peas. There are other things I add to it such as red algae, garlic extreme, spiralina powder (not tablets), flakes, etc. I use a binder that keeps the mixture intack in 80+ F water, so it doesn't disolve on the bottom. Basically, 1lbs of this feeds my 6 discus (4 large + 2 med) and a bunch of little fish for almost 3 months on 2 feedings per day. However, if you are trying to grow out you babies\juvi discus you will burn through it much quicker.
15 bux a pound!
