Well, there you have it; a "hypothetical life history" has to be the best kind of all.
So, their hardiness in non-optimal conditions allows them to survive and even spawn in these ponds cut off from the main flow. Somehow, the "hypothetical life history" extrapolates that those individuals comprise the core population; all those fish that return with the receding waters are relegated to the status of a "peripheral river population", serving merely as a "buffer". That life history is hypothetical, indeed.
Do they hypothesize how close together those clutches of eggs are laid in even the most crowded conditions in the wild?
But it sounds like you have it under control; you know they'll be fine, they have lots of room. That being the case, I won't wonder why this thread, and the original question it posed regarding "mysterious" aggression, even exists in the first place. Cheers, and good luck!
