Ah yes actually I do what David does, but with a "twist" I pour out the water into my pond which contains bettas or Guppies and Utrics. My water dish also gets some bloodworms and some tiny freshwater crustacians such as moina/cyclops, which gets dumped into the pond too. Besides I think the CPs do appreciate that the water be changed from time to time.
I do the drying out technique like what JK said for my Droseras.

ps. Riverstein said that the only CP that he knows that catches Mossie Larvaes well are Aldrovanda, but not sure if they will thrive in water tray.
