    Brine shrimp does tend to be easier (and smaller and more nutritious than daphnia) to culture than daphnia though. I had no luck with the Sera brand - couldn't even get it to hatch! The Ocean Nutrition brand hatched every time for me. You will struggle to have enough daphnia for a steady supply of food, I think. Don't start culturing your BBS until the eggs start hatching. Brine shrimp takes 18-24 hours to hatch, and the larvae will live off their egg yolk for the first day. Only once they are moving around, will they start to eat. If you feed them before they are ready, you could just risk fouling their water.

    Use a coffee filter and filter the brine shrimp through it. You can buy the filter papers anywhere. Then rinse the filter paper with tank water a few times over a sink. Then put the BS in a jar containing aquarium water and then you can transfer them to where the babies are in the tank. I do this for fish fry and have no problems with fish deaths.

    I have seen brine shrimp nets at many pet stores. Its a very fine net, I have used it many times for rinsing freshly hatched brine shrimp.

    @Simon sift them through the toe of a stocking placed over a jar or fruit juice bottle.

    Please state location. If you want, you can go to exotic pets.
    Ask for Steven (manager) the only place so far that I see live daphnia.

    @Simon - I used to rinse the baby brine shrimp in those cotton face pads (the round disc-like ones), as I couldn't get hold of coffee filters (woolworths was all out of them). However, I soon got tired of this, and developed a sort of guideline for myself when introducing salt water to the tank. For every ml of BBS solution I put into the tubs, I'd remove at least 20ml of water from the tub and replace it with fresh water that had been pre-conditioned and buffered to the correct pH and kH. I had 9 babies to start with, and I have 7 now. One, the cat fished out and ATE when they were 3 weeks old, and the second one died at a little after 4 or 5 weeks. They're nearly 8 weeks now and they're doing so well.
