Popcorn Brine Shrimp!

Well I am in the middle fo my third batch of doing this and it is simply amazing how much the fish like them. I am simply taking really old brine shrimp eggs I have had for well over 2 years, decapsulating them, then putting them in the microwave and literally popping them. They expand to a huge size, comparatively, and the fish go nuts for them. I really think that they would be an awesome first food for any and all live bearer fry as well as many egglayers if they are large enough to eat them.

Here is what I do:
I take about 1 tsp of eggs and rehydrate them in luke warm water, about 3 tablespoons, and wait for about an hour mixing them up as often as I remember to. You can do this with an airline to really keep them suspended and possibly get better hydration. Next, I add 2 tablespoons of Clorox unscented bleech or any unscented bleech and let them sit for about 10 minutes or until all the eggs have turned an orangish color. I use a large test tube I have an shake it for about 10 minutes or until I see nothing but orange eggs. The hard part is rinsing them and getting out all the bleech. I simply rinse them many, many times until I can not smell it anymore. Then I rinse them 2 more times. Before popping them, I will add some dechlorinator to make sure it is all neutralized, just 1/4 tsp. or so just to make sure. Then I put them in a coffee cup filled about 3/4 full and microwave them for 2-5 minutes or until they all turn bright red. The volume increases a lot, maybe 2-300% or more and are simply fed to the fish. The shell is no longer a worry because the decapsulating process disolved it away so you feed them directly.

I am actually gonna get some decapsulted, non-hatching eggs so that I no longer need to decapsulate them but figured I would try it to make sure it works before buying them.

If you try this, please post about and what fish you fed them to as well as how they reacted to them. I think fry will love them and be much healthier from feeding them the popcorn shrimp because the nutrition should be higher and you don't have to worry about not having enough hatched brine shrimp on hand or trying to scramble to et them hatched when an unexpected batch is found in the tank. Not to mention the problems with seperating egg cases when hatching them.

The first image is of the eggs decapsulted, the second on is of the same eggs popped. The volume of the eggs doubled if not tripled. They are very light and fluffy. I think that they should be very useful for a lot of fish and a lot of fry.

My fish love them even more than before. The popped eggs stay suspended extremely well in the water column and my swords and tetras spend a lot of time picking off every single egg that is floating in the tank. I thought there might be a poblem with left over eggs in the tank but the fish are more than happy to pick them off even though they seem so small in the tank.

Just wanted to make sure that if any of you ever try this that you put the eggs in water before microwaving them! They do not pop like regular popcorn but pop in the boiling water. I actually sent this tip to someone and forget this tid bit and I guess it resulted in a pretty foul odor because the eggs burned in the microwave.

Make sure to put water in the coffee cup or whatever so they eggs don't turn into brown ashes and really annoy the significant other or the neighbors.

fish_4_all, I am wanting to try this however I don't have a microwave. Would using the stove-top work equally as well? Thanks for any info you could provide. Luis
