Using my trusty new Digiscope, I looked at some tiny critters I had
isolated from the detritus on the bottom of the container of fish
water to be used as house plant water. I thought they might be the
hard shelled seed shrimp, but was pleasantly surprised to match them
up against a couple of pictures from the Encyclopedia of Live Foods
by Charles Masters, 1975 edition, page 116. I am going to attempt to
rear them in different systems using hay infusion, bacteria,
detritus, and the trusty green water.
Please view the two attachments.
From caudata.org, I found an intesting paper:
Daphnia: An Aquarist's Guide(a Caudata.org web site)
Version 3.2
written & compiled by John Clare
He states:
Bosmina coregoni is a rather small species (about 1 mm in length) and
is found in weedy ponds and canals. Due to its small size it is more
suitable for use as a fry food than other Daphnia. It is a very
active species and can often be confused with other small daphnids
without the aid of a microscope or high power magnifying glass. Its
body shape is shaped rather like a pea which has started to sprout.
It is commonly found in Northern Europe. Interestingly, many "Moina"
cultures are actually Bosmina cultures.
