Good morning Stefanie.
🙂 A bit dramatic topic for a ‘good morning’ 🙂 .. eating ones own fry :unsure:
But interesting it is.
My experience is indeed like yours, but I have never seen it happen though.
I wonder though a bit, if its something which is more likely to be a problem when you have more than one pair in the tank. In my experience certainly tanks with more than ‘the breeding pair’ is much less likely to produce offspring. Whereas tanks with only the parent pair – though I am sure some eat their offspring, other pairs do not do it in the same degree.
My p.harveyi seems to be much less prone to this habbit, and quite often have big numbers of offspring surviving.
But your observation of the fry and their behaviour is also really interesting, because for sure the paro fry have learned to being as invisible as possible.
