Remember that very,very few tadpoles do make it to maturity. Much
fewer than one per mass of spawn.

But that's more from predation than simply failing to grow, surely?

Just what I was wondering. Thanks for asking.

:-)

As far as I can see, I have just one of the little blighters left from
several clumps of spawn.

I have also gained at least two newts which might, I suppose, contribute to
the tadpole deficiency?

The water has been gently circulating throughout the incubation and growth
period to clean and oxygenate it naturally.
