I am sure that they are very close, common recent ancestors.

What do you think is the reason for the long metamorphis and high mortality?

Hi Jake,
Reaching meta at 20 days is in no way a long larval stage.
Your 2nd question is harder to answer.I don´t know,but I suspect that this larval mortality is related to so many others many people suffer,meaning same or related issue killing larvae. :?

Hi Luis

You mentioned in other posts about longer met time, I agree 20 days isn't bad. Could diet size be a factor and only the larvae able to take larger prey surviving? I am clueless. But want to explore a couple thoughts. I read on another site of a researcher rearing smaller pods at cooler temps, 20 C and lower of an S strain. As luck has it my new residence has a huge, and cool basement.

I don't think its water quality with you and so many others having had such similar results, it seems that prey size might be the murphy hanging out here. Whats the coolest that you have had eggs hatching at? Or have they all been the same or close?

I really admire your staying with them so long. I have no doubt that you will make the breakthrough .

No,Jake I haven´t played with temps.I will die swearing that some environmental factor kills larvae,all larvae. :wink:
Check PM.
