Brine shrimp disappearance?

[ButtercupSaiyan]

Hi all, I grabbed some live brine shrimp as feeders and we poured approximately one-fifth of the bag into our vivarium. There were tons visible everywhere, and when I woke up this morning, they're all gone! Do they die rapidly when introduced to a new environment, were they probably all eaten by the Triturus Dobrogicus, or do they hide in the gravel?

I know this probably sounds like a very silly question, but I can't figure out if the sea monkeys have simply squirreled themselves away in all the nooks and crannies or if this is common.

Thanks for your time,
Ashley

Nevermind, the tank is fresh water and the shrimp were put it at approximately nine PM last night. It's been about twelve hours or so since feeding.

Hi Ashley,

Brine shrimp do die relatively quickly in fresh water but they don't just disappear. No corpses means they were dinner.

As their name suggests, brine shrimp live in salt water. They don't last long in fresh water.

Hmmm, I have lots of daphnia in local waters, I live in Florida in a city with lots and LOTS of lakes ... is there any danger of chemicals, disease, or parasites, feeding captive-bred newts wild daphnia netted out?

They live around 4 hours in fresh water, so after 12 hours anything uneaten is long dead. If you are feeding freshwater animals with brine shrimps, use small portions as often as possible. Good thing is to vacuum the gravel pretty often. I usually vacuum once-twice a day (depends on how many animals I am feeding) just before adding another portion of shrimps. Anoher good way of dealing with dead Artemia is to add some snails. Dont worry that snails will polute with they feces - they not even close as dagerous as dead naplii.

Some breeders use wild cought daphnia, but I wouldn't risk. Daphnia is really very easy to culture. One 10 litre bucket would be sufficien to culture enough Daphnia to feed around 10 newts size of T.vulgaris every other day. Its good idea to have at least two cultures.
