    My buddy came over to help me out with the seahorses. He started two brine hatcheries for me. The bottle of decapsulated brine was just about empty. So he adds some saltwater to the bottle to get out as much as he can. He forgets to throw the bottle in the sink to be cleaned. It sits on a shelf over night with about 1 cm of water in it. There was no water movement, the cap was on the bottle. The brine hatched! I decided to leave it so I could show my careless friend his science project. After two days I add some more water, removed the cap and added some live phytoplankton. Five days later they are still alive.

    Now all I need is about a thousand 948ml empty pepsi bottles.

    If these make it to be adults, I'm putting Scott in charge of the brine! :lol: That will teach him! He's been having a ball with this. He walks around telling me I'm cleaning my brine to death and not to touch his science project.

    Jealous, i still wanna grow some brines to full size, it makes you think about all the people that go through so much effort to grow them(water changes ect) and you seem to have it happen almost by accident!

    Here is a pic of Scott's Pepsi bottle/brine grow out next to mine. I only keep brine for about 48 hours before feeding out.

    Here is a close up of Scott's bottle. Sorry for the dirty bottle, but as you know, Scott didn't clean it first, and I'm not allowed to touch it! ;) This is day six:

    For the time being it isn't worth the hassle. I can't do it here. Scott's house is a 30 minute drive. I've been lucky enough to get these little guys to take frozen food amazingly fast. These parents have really produced some strong fry. If I push it, at 6 1/2 weeks they never see brine again. Not bad IMO.

    Sorry to ask, but is it very unusual for the brine shrimp to hatch in a small unoxygenated bottle of salt water?

    After all, thats pretty close to their natural conditions... Hypersaline lakes and some spp even occupy ephemeral puddles... I always thought these were like the easiest things in the world to hatch...

    have you ever tried feeding them egg yolk? I had a culture going on my desk in my lab in a little jar when i was doing my zoology honours... Fun to watch them zooming around upside down :)

    No, not unusual in small volumes. However, when you need larger volumes of brine, you must keep the eggs moving.


    They are pretty easy to hatch. Hatching has never been a problem for most. This is the first time I've ever seen it done without water movement, BUT it was such a small volume, so I'm not overly surprised by the hatch. I am surprised that they are growing while being kept in such a small amount of water, lack of food for 2 days, no regular maintenance, and no added oxygen.

    No, I have not tried egg yolk. Please explain your procedure. How much food, how often? How often did you do water changes? How long did they survive? Did they reproduce? What was your stocking density?

    My son Rogan just puts them in a 5 litre bucket and adds leftover nhbs from feeding his baby Banggais, with no aeration and adds phyto when he splits the cultures and they are doing well.
    I use half the 220 litre drums with artemia and have no aeration and let them do their own thing (although I do not really use them for feeding), not even feeding them.
    I am busy moving those into a chopped off 1000 litre drum and setting up phyto and rotifer in thousand litre drums and will be aerating these cultures and using the phyto for the rotifer and artemia as well as possibly using the rotifer to feed the artemia. We have recently set up an Upside down jelly display and want suitable foods to use as well as nhbs to cut costs and the rotifer should be good for tat plus occasionally harvesting from blooms of nhbs in the artemia culture, after keeping in an egg cyst separator.
    In the past I have used various mixtures of yeast for feeding and heard of the crushed cooked egg yolk method. I think if you have phyto or even better a variety of phyto then using yeast or egg yolk is unnecessary.

    :slayer:Wow Steven how log has your upside down jelly tank been running & was it a tricky build? I have been interested in making 1 myself but just worried about power cuts as ESKOM is not a fish keepers friend. If you have the builds plans pretty please could you pass them on? ;)

    They are easier than normal jellies, light flow with a soft sand bed and 10 000 kelvin BLV 150 Watt MH. They sit upside down on the substrate and also filter feed on rotifer, nhbs, etc.
    You do not need a specialised tank.
