Well,
It would be quite an original death: choking in Pachyhynobius eggs while trying to suck them out with a straw... Unfortunately, I had to do something: eggs neighbouring the affected ones started to die. I first tried to aspirate the eggs using different sized needles. Didn't work. Moreover, the outer layer of the egg sack also showed fungal hyphae. Hence, I "surgically" amputated the bad part. Not easy since the eggs stick together very well. The remaining, hopefully still viable embryos were not damaged in this process so there is still some hope... I transferred the other egg sac to another container to decrease the risk of contamination.
