Mine never seemed to like Daphnia that much. Too crunchy? Too big? [I had
magna].

Not nearly as big, but easy to see in a dark mop. I have not measured, but
would guess them at just about or under 1 mm.

Eggs are easy to see in water. The babies are not really all that tiny, but
the bodies are transparent, so seeing a sliver of glass in water is
difficult. The eyes are tiny, too, but can be seen without a magnifier, once
you have found one. The irridescent reflector between the eyes, on top of
the head, is the most visible thing, if you have a flashlight.

That list of plants may not like the conditions. The Val like quite hard,
alkaline water, and the Water Lettuce does not usually do well in tanks. It
needs so much light that larger plants get burned by the lamp heat, and it
hates any cover-glass drip, normally. The Salvinia needs plenty of light,
like the Pistia, but the ANN love its roots. It, too gets moldy under a
cover glass, sometimes.

Shipping should be OK right now from much of the country, if the shipper
waits for a few frost-free days. A mop can be mailed in a fish bag, with
little excess water, wrapped in small bubble pack, and shipped Air Mail in a
box designed for shipping video cassettes.

Good luck,

Wright
