It depends on the size difference, tank mates, tank size. In the grow out, between the 3-4" baby and 10" gold, I could see a certain amount of malcontent with snapping etc but, crucially, they were both feeding side by side and I wouldn't have said it was constant. In the main tank, the large and med don't generally have spats, though occasionally the larger one will spook the med while resting, instigating a half chase. On the rarest of occasion, there may be one or two nasty moments leaving a few missing scales, torn fins etc. Really though, their tank mates keep them too busy to think about chasing.
I guess I've contradicted myself in the previous post stating there was zero notable aggression then mentioning that there actually is a small amount but really it has never been terrible. I have had the Curupira brutally savage the medium Gold, though, hence why it was in the grow out for recovery. I let it put on a bit of weight and heal before putting it back in the main tank. 6 months on, everything seems ok.
So then, that leaves me with questions like how big is their tank, is it just a pair, what are their tank mates and how big are they? It maybe that in a tank where they are nearer the top of the pecking order, it causes them to constantly vye for dominance.
