Hi Tim
here in the Moens Lab in Seattle we use small plastic tupperware
containers. They hold 500ml if completely full so we put 300-400ml in
them.  They have 5 holes cut in the lids.  They stack on the bench
such that we have 8 columns wide and 6 columns high (1/2 of a 96-well
plate).  To fill 48 "tanklets" we make up 20 liters of system water
with AmmoLock (2.8ml/20L; Aquarium Pharmaceuticals) and Stress Coat+
Fish and Tap Water conditioner (5.3ml/20L).  We leave the fish in the
tanks, without changing the water, from one to 5 days.  When finished,  
we put the  tanklets through a bleach process and then send them down  
to glassware
for a final washing (water only).
