I found that if you buy daphnia near the afternoon, a significant amount of them are already white (dead). So, I went one early morning and got few bags of FRESH daphnias ... almost all red!!!

Placed in 1 week old water + green water + yeast + slow bubble + in steroform box. Everything by the book!!!

OK, so this time, they lasted 4 days!!!

So, to answer the original question of this post ... I keep all sorts of fresh and sea water fishes, and also corals ... but in my years in this hobby, I must say that breeding live daphnia is the MOST DIFFICULT for me ... but maybe it is just me!!!

OK, there is a chance that my tap water has too much heavy metal, and it is killing these buggers ... ONE LAST CHANCE!!! This week, I will use FILTERED WATER and try again!!! And if it does not work ...

By the way, I know water with $#!+ is good for them ... but many people also have success with just using yeast ... so, for health reasons, I will stick to yeast for now!!!
