Our Tapered Tailed Guppy Fry

[Guppiesgalore]

These guys are a few weeks old now, and just starting to see some yellowing colour in some of their tails.

I do not have any adults with this tail shape, so it's very interesting for me to see them develope a different shaped tail.

The younger guppies in the pics you can see have normal tail shapes.

I have to wonder, could it be they are just clamping their fins to their bodies?  Because they kind of look like they're stressed.  I don't mean to be pessimistic.  Perhaps you are correct.

I'm not sure exactly how you could think that a fish could change its tail shape because it is stressed. All of these fry are from two different spawnings. Older ones as well as younger ones have normal tail fin shapes.

All I was saying was that I've seen some of my fry have clamped fins (because they are stressed or unhealthy) and it makes their normal tails look pointed.

Sorry, but they also all look clamped to me as well.
 
I would suggest checking the water parameters.
