Need advice : Daphnia with furry coat
Hi,
My daphnia seems to be having a problem.
They seem 'furry', like having a white fur around them.
And they are swimming slower. Many are dying also.
I changed water and they seem better but I'm afraid they're
lack of food since now the water is so clear.
Also before they develop their fur coat, there also seem to be
some white patches under their carapace.
I feed them Gram flour and yeast which i try not to over feed.
I rear them in a square plastic container (28 cm x 34 cm x 12 cm)
with about 3.5 litres of water. I put some calcium carbonate tablets
in the water (from health food store).
I estimate that there are about 200-300 individuals there..there are many
tiny ones too but they are also coated with 'hair'.
I've been keeping the culture for 3 weeks now beside the window and with a
small fan blowing over the surface to stir the surface. No aeration. They
started dying when i first start the culture, then increased in numbers but
now they are starting to die...slowly.
I'm in Glasgow, UK and temperature here is probably around 21-24 celcius
now.
Can anybody advice me?
Thanks
Adrian
