super fry

Is it common for 1 or 2 fry to develope way faster than the rest?

Yes it is quite normal. As with every living thing you have your quick starters, your "average" and your slow growers (runts). Out of one group of platies I have 6 that are at leaast 1/2 inch larger than the rest and I have 3 that are 1/2 inch smaller. So dont fret about the size, in fact if you watch them you will probably find that the larger fish are the most aggressive at feeding time. Good luck with the fry

A couple of months ago I read an article someplace about interesting things a fishkeeper learned while raising rainbowfish fry. The author explained the whole scenario of some fry grow larger, most mid-sized and some small. He said he learned that if he identified the larger fry and removed them to another tank, then another "wave" of the mid-sized fry grew in their place to fill the spots left by the previous large ones - as though there were some self-correcting natural system that a particular statistical percentage of fry among a population reared together must be larger, mid-sized, and smaller. It could just be, though, that there are some kind of "natural selection" qualities that are more prolific in a particular percentage of any population that allow them to grow faster (i.e. get more food, less harrassed by peers, etc.).

Just thought it was interesting.

pendragon!

Yeah, it is very interesting, but what to do with the runts? I just have one left, runt that is, the other runts died in a bout with fungus.
