My brine shrimp i hatched for my convict cichlids did not die after week, they lived for 3 months, got to the size of sea monkeys, bred, then died... lol
My sea monkeys lived for 2 1/2 years. the first ones died after about 6 months, but the eggs that floated to the top and go stuck to the side of the tank wall dried out and hatched, and so on
It is very fun to shine a flashlight in front of the tank at night and see all of the shadows moving around.... they look kinda creepy at 3 feet in length
I think triops are funner. They grow alot larger, have three eyes for their entire life (sea monkeys have 3 eyes for the first 10 days of their life, before they first molt). Triops are feirce, it is fun to watch them prey on daphina. I also, with the san fransisco bay brine shrimp, used the meathod to get some sea monkeys into fresh water, then i fed thme to the triops. It was so fun.
Kinda sad though, the sea monkeys didn't even have a chance
