So I had the honour of hosting Heiko Bleher for dinner last Friday night, as he was in town for the Aquarama exhibition held in Singapore every 2 years. He came by my place to see my tanks, and when he saw the C. "Atabapo II" in my tanks, he frowned and said that they were from the Rio Inirida instead and not the Rio Atabapo. He also said that the pikes came from whitewater conditions and not blackwater.
Anyone able to chip in on this startling comment from Heiko? Given his expertise in all things aquatic, I don't think it's very likely he's made a mis-id? If so, that means that all along we've been id-ing this pike wrong!
