Any ADF tadpole experts?

when you say full water change...do you mean 100%?


if so - that was the culprit.

with tadpoles, they are so sensitive to changes in their water, that I would never do more than 25% at a time.

I did a full water change this morning (same water as always, dechlorinated last night, heated prior to moving the tadpoles) and they ALL died. Something must have gone wrong. Next time, if there is a next time, I will be hyper paranoid about testing water before I use it - the only thing I can think of is there was some change in ph in their tank before I moved them.

That's disappointing. I usually advise anyone trying to breed these frogs for the first time to be prepared for disappointment because it can be very difficult to get the tadpoles through the first couple of weeks.

I don't really understand why you felt it necessary to change the water if the tadpoles were thriving. It seems unlikely that they produced any significant waste. Any dead shrimp or other detritus could have been syringed out or siphoned using a short length of air line, which would have kept conditions stable. Personally, I've never worried too much about pH or other water readings.

On a more positive note, once the frogs start laying eggs they usually lay successive batches every few days so you could soon have other opportunities to try and rear them. As you've already been advised though, the female will need time to rest otherwise continual successive egg production will weaken her.

Good luck.

Geoff.
