The 20th day, collapse!

There are just a few zoeas floating. The majority died off in the last two days. I am not sure what was the problem this time.
I was looking forward to raising Amanos. I will probably try breeding Amanos next year again (will rest from them a bit). Instead I will try to breed less demanding species like Neocaridina denticulata sinensis-red and some other nicely colored Caridina/Neocaridina species, that desire no marine/brackish condition for rising the young.
