Or do you want one for raising a relativity small amount as just a treat for your fish and for the fun?
If so I'll probably get back to you tomorrow on the my method (I'm tired for once lol), but you should decide on what size of tank you want.
My method gives you a low yeild of brine shrimp, but they last for ages, will breed, and the water stays clear. Basically just a bigger version of the sea monkey tanks without paying loads for the stupidly small sachets
You don't need to aerate the water either (something the sea-monkey company made up to make you buy the 'million bubble air pump').
550g is alot, I have a 30g sachet of mixed Artemia species and I don't think I'll ever have to buy another! (and I actually got that one free anyway!)
They shed their skin every few days while growing to maturity, then its less often. You can use an eye dropper or syphon the old skins out. You want to remove them so they don't rot and cause ammonia. If you get an ammonia reading in the water it can kill them.
They are a bit like Daphnia and can produce live young when conditions are good, but eggs when the lakes start to warm up and dry out.
Artemia eggs have to dry out before they can be hatched. It's an adaptation to their natural environment (salt lakes) where the lakes fill when it rains and the dry eggs hatch out and the shrimp grow and breed. The adults produce eggs that float around and get washed up onto the shore where they dry out and remain dormant until the lake fills up again.
I currently have two tanks os sea monkies, one around 4 months old which I believed was thriving and the other around a month old.
I followed all the instructions, added the water purifier, waited to add the eggs, fed at the recommended levels and times until grown.
My first tank (4 month old) has 1 adult sea monkey that has developed some black spots on their extremities. I've been trying to source some sea medic or red magic in an attempt to save the rest of the tank.
I've only replaced a very small amount of evaporated water, using bottled distilled water and now that I have a fair population within the tank, I feed them once a week with the large spoon. I'm not sure why one has developed the black spots. Any help would be appreciated. Nothing has changed, they're on a window sill that does not get direct sunlight.
