I would like to know if any of you breeders did notice a strange dying of kaiseri larvae in the first days after hatching.
The problem I desrcibed in detail here: http://www.caudata.org/forum/showthread.php?t=53674
This year my kaiseri girls laid a lot of eggs but the survival quota for larvae is as bad as last year, around 30% are not affected and survive the critical first 2 weeks.
After that they grow and feed without problems.
An addition to my observation last year:
1. adding a medicine (EsHa 2000, methyl orange) 50% of larvae survive
2. adding nothing, just changing with clean water all 2 days: 10-20% survive
3. putting the eggs before hatching into a well planted small aquarium with a lot of tiny food and microbes: 50-75% survive
Does it happen only in N. kaiseri or in other Neurergus species as well?
Did anybody observe this phenomenon with his/her N. kaiseri?
