kiwifeather said:they are starting to have small scraps with each other, nothing major although one has tiny nick out of its tail now. I'm guessing once I finish off the school they'll settle down a bit.
This is actually a good sign
From my own experience neons only scrap when the conditions are perfect for breeding. It could just be that they are gearing up to spawn or may have already done so otherwise they're quite placid towards each other and only "scrap" or jostle for dominance when their water parameters are 'just right' so to speak.
