At 20 years old I bought 2 wild Blue Heckel Discus in Tucson AZ. At that time Discus were said to unkeepable in an aquarium. Is was back on 1982. I put them in a 75 gallon tank with all my other fish, with just tap water. They lived for years until I moved Back home to MN. I have bread Discus. I have a 75 gallon with 5 assorted hybrid Discus. But the Discus I love the most is the Red Spotted Tefe Green. So I ordered 4 Red Spotted Greens from Rain Forest farms and tom has been delaying delivery for over three weeks. Please let me know if you dealt with this company? Please let me know.
