The Triops have started on solid food. They seemed un-interested in the food at first, but once the pellets swelled up with water the little darlings had a nibble. The instruction booklet says that after a week you can feed them tiny pieces of carrots and fish. I had some Australian Snapper fillets in the fridge for my dinner, so I snipped of a little piece and chopped it in to Triop sized morsels. Ive never tried snapper before, but it must be delicious - judging by the macabre feeding frenzy that ensued. Mental note: be careful about getting fingers in the water when they get a little bigger. Triops don't want to be fed, they want to hunt. Can't just suppress 65 million years of gut instinct!
Update: The snapper was indeed delicious.
