Fry update

There are quite a few Macropodus fry around - most of them are clinging to floating vegetation, but there are a few free-swimming individuals. That raises a question - are two-day-old fry going to be doing any swimming, or are these a mixture of newborns and 10-day-old fry? After I saw the male Macropodus eat most of the fry, I assumed that there were none left. While that still seems more probable to me, it's also possible that there were survivors of the original batch. I'd say "we'll see", but no, not really - the odds of many fry surviving in the community tank is pretty slim, and even if they do, the radically different growth rates that I saw among the first batch of fry make it impossible to connect size with age.
