OK, so I found lots of really tiny platy fry in my tank yesterday. Am thinking this has to be my last batch as I only have females and I've had them for 2 months or so now. Anyways, I put them in the nursery tank with 1 month-old and 2 week-old molly fry. Didn't the molly fry start giving chase and nipping at them? Now they ignore the food I give them as they find hunting more entertaining! Grrrrrr. The cheek. Don't they realise the irony?
