Just for the next few days, I'm looking for some adult artemia until my freshly hatched ones get big enough to be noticed by my fish.
A nice big bag of them would be ideal.
I've called almost every private LFS in Perth, nobody can get supply of them now, at least not reliably.

 

Livestock
Name: Artemia
Size: 2-4 weeks old
Number: 50-5000
Price or a ballpark figure: Don't charge me an arm and a leg

I think that you may misunderstand the way in wnich brine-shrimp are best used. Newly hatched shrimp are ideal for feeding fry, though some larger fish (particularly plankton eaters) will enjoy them. To be nutritionally useful, the shrimp nauplii need to be used within 6 hours of hatching,

You say you wish to grow brine shrimp to a size large enough to be noticed by your fish. Growing these oprganisms requires a good knowledge of certain husbandry techniqes, and is never really simple. It will take at least as month to raise them to near adult size, and to be nutritionally useful it is necessary to ensure that at the time of feeding them to your fishes, they are "gut-loaded" with nutritiuos food. In effect, adult brine shrimp can be considered just a way of delivering suitable food to fishes that otherwise may not be easily persuaded to take such foods.

In real terms, even if you can successfully raise brine shrimp from the nauplius stage to adults, the best results will guarantee only about a 20% survival, and 5% is more likely. It can be a lot of work for minimal results: and needs consdiderable resources in the way of materials and knowledge, including good volumes of heated water since growth is slow below 25 deg. C, and in overcrowded siuations.

I'm well aware, thanks  I don't have particularly high hopes of finding any, but if you don't ask...
I feed the newly hatched ones to my smaller fish.

They will not be used for nutritional purposes, just for enticing some reclusive fish to eat over the next few days. There are a number of other small swimming invertebrates that would also work, but I don't feel comfortable posting a classified ad seeking them...

Live mysis would be ideal, but I haven't heard of anyone in town doing it.
