Triops

I wouldn't trust much of anything from wal-mart. I would just stick to the usual food since "Jurrasic creatures" may really foul up your water.
 
Do a little search on this page for a thread titles "sea monkeys". There you can read in detail what these triops are.

Fairly interesting creatures....
 
I love triops. I hatched a bunch once, only one or two hatched, and only one remained at any rate after a week or so. When he got a little bigger I put him in my DP tank and he was so much fun to watch. Ugly little buggers but awesome. Then my GSP moved in to town for a day and I couldn't find the triop again...
