So the eggs more than doubled in size and, when I was looking last night, I noticed there were markedly fewer of them...then a little fish popped out of one and disappeared.
I then noticed Mother was pecking at the remaining eggs and disappearing around the corner of the filter box, out of sight.
So, she's either moving them to somewhere she deems safer, or she got peckish.
Given that this is in an active community tank, I'd be surprised if any fry survive, no matter how determined the parents.
To try and help out, I added some more 'feathery' plants and have put some liquid fry-food in the tank, to provide for any little ones and, at the very least, to facilitate growth of infusoria.
