Thomas I don't think you would have a problem raising small wild Altums to adulthood at all. What you have done with spawning and raising your CB fry is amazing. Just like Altum85 I have also purchased Altums from John Kreatsoulas in the past. He was my go to guy with wilds of almost any species. Unfortunately he had a massive cardiac event that forced him to retire. Bless him, I hope he is doing better. Anyhow, John along with a few other importers knew how to prepare for their Altums arrival and connected with suppliers who went a step further in preparing their holding facilities in South America. I believe this is why wild caught specimens are doing much better when arriving in the U.S. Ed Ruiz, an Altum guru, once said to me that finding a good supplier is half the battle. I totally believe that. In my opinion most hobbyist don't want to mess around with R/O water so the CB are much easier, and conservation is very important. I have one question my friend Thomas, How did you get that fish to grow so big.And are as easy to take care of as any domestic angelfish of course !!!
That way we all can enjoy this.
