I cleaned out my sea monkeys tank. I took all precautions such as getting filtered water and waiting several hours before letting them get into the new water. I googled on if I should clean out their tank or not and it said it didn't really matter but if it bothered you then go ahead. It bothered me. But now they are not able to swim and they are kind of discolored. What's wrong? I don't want them to die!!

To be perfectly honest, once they are hatched you should leave them alone. Just feeding and occasional water top up is all they need.
They will not last for a long time, after all they are simply brine scrimp.

So there is no saving them?

I did a little research, and found a few sites that all say the same thing. The average life span for a sea monkey is 3 months. Anything more is just plain luck.

They're meant to be a fun thing for kids. They really aren't long lasting, and once the 3 months is up, their time is numbered.

It's nothing you did. Just enjoy them while you have them. :)

Sea Monkeys are just brine shrimp. Brine shrimp have only one purpose.. food for fish. They don't live forever and their water requirements are relatively easy.

If you decide to hatch brine shrimp again in the future, you can clean the tank with vinegar. Wash out with HOT water and then fill with the cold water and allow for the temperature to rise to where the brine shrimp need it to be.

Like already state, since they're already hatched, then don't worry about the tank being cleaned. Any disruption of water environment will probably kill them off and shorten their already short life span.

Wow.. Mine lived for about four months.. So I guess I did pretty good until I cleaned it :(

Lucky098 is correct.I use them whenever I want to raise some angelfish. They are necessary for newly hatched fish.They do best with live food.
They require a salt water environment.

Using an air pump,run some tubing with about 1 ft. of ridged tubing at the end into an empty plastic liter (soda)bottle. Add 1 to 2 teaspoons of kosher or aquarium salt(mix),add an 1/8 to a 1/4tsp. Of shrimp eggs. Place a 40-60 watt bulb within a few inches in lieu of a heater. You will have hundreds or thousands of shrimp in about 18 hrs. To keep a supply on hand you would start a 2nd bottle 12hrs. Apart. This way one would always be hatched for a days feeding. Whatever you don't use throw out, they go bad.
I have eggs in the freezer for 10 years now, and they still hatch when I need them. They are very expensive.

Let me clarify: Shrimp require salt NOT angelfish!

LOL 4-6 months is not a very long lifespan in the wish world. A year isn't even that old...
