Daphnia habits
Do you think that daphnia have a sense of polarity? I have a 10 gallon
tank that is divided in half by a siliconed piece of glass.

The daphnia always seem to hang out in the same corner of the tank (X).
The tank is plain with no lights, heat, filter. It is by a window but
they do this weather it is day or night. It is hot during the day and
cool at night (they respond the same way in either temp). each side
houses a trio of killies. Each tank also contains a cool whip container
that is placed in the very center.
Any ideas?
