Re: Live Foods Digest V3 #212


My indoor daphnia are reddish and the outdoor ones are usually a lot darker, 
although they become reddish too when they "pulse".

I've read that daphnia redden when they are stressed and the hemoglobin in 
their blood increases.  So maybe "darker" is the natural color of healthy 

I'm sure others know more than I.

Good luck!
