Steve, with the large amount of space, and the number of fish that you have. How many fish by the way? Don't you think that they can avoid aggression? Rex could probably answer this better, but my understanding is that many fish allows the aggression to be spread out. So you have quite a number of fish, and quite a bit of space for them to retreat to. Just my guess, but maybe you should be more concerned about the new pool, could it have any treatments that make it unsafe? Or could your trace amounts of ammonia be taking a toll? You are doing well so far, and the loss of a couple fish is to be expected. But two in a day would lead me to think environment rather than aggression .
