And on a more humorous note, http://www.seamonkeyworship.com/ offers the following advice:

SOME HELPFUL HINTS FOR RAISING SEA-MONKEYS®

1. don't lie - Sea Monkeys® don't like it when people lie to them anymore than people do;
2. don't give them bananas - they may be monkeys but they will be suffocated by the large banana in their little tank;
3. don't eat them - you may enjoy the momentary taste but you certainly won' t have the fun of watching your Sea-Monkeys® grow;
4. don't scream "Hey look at the Sea-Monkeys®" at them - they don't like to be reminded of their existence. (Sea-Monkeys® are docile creatures who prefer to remain clear of existential thought.) Similarly, Buddhist koans such as "what is the sound of one hand clapping" might make the Sea-Monkeys® realize the meaningless of their existence and this could cause mass Sea-Monkey® suicide;
5. don't force your Sea-Monkeys® to mow the lawn - they have a severe allergy to freshly cut grass;
6. don't let your Sea-Monkeys® operate heavy equipment while under the influence of cold medication as it can make them drowsy;
7. do involve your Sea-Monkeys® in political discussion - despite the fact that most Sea-Monkeys® lean to the left;
8. do cover the Sea-Monkey® tank while engaged in marital relations as Sea-Monkeys® carry camcorders and aren't afraid to sell those tapes to "Hard Copy"; and finally,
9. If you run out of Sea-Monkey® food, please don't feed your Sea-Monkeys® just anything. Timothy J. Isham figured he'd feed them some spaghetti-o's. The can must have had botulism or something. Please don't feed your sea monkeys anything out of a dented can.
