Okay Mike,

I set up the bottle, got the airline rolling in the water and put the eggs in. Now I have to go read what to do next. :D

Then thats when I dump them out through a B.B.S. net? And put them beck in the air bubbler until I can get to Mikes?

Thanks, Chris

Chris:

If at all possible add a heater to the hatchery. they hatch better and faster in the mid 80's then at room temperature.

Straining BBS isn't as easy as just using a net. You need to wait until things settle out as unhatched cycsts will fall to the bottom and empty shells will float to the top. The BBS will basically stay in the middle of the hatchery. They are attracked to light so you can use a fine beam of light on the side of the hatchery to attract the BBS to a place you can syphon them off. It's not exactly the easiest thing in the world to syphon but it works.

if you want to keep them alive for a few days photoplankton is the best food source however powderized spurulina is also accepted. feed VERY LITTLE or you will have problems with poluted water.

Thanks Michelle,

I have a 3 ltr. plastic pop bottle standing on its top in a "Q" tank. Its heated and has a P.H. The airline runs to the bottom bubbling up through the eggs.

So, they should hatch Wed.? (I put them in on Mon. pm). Should I use a turkey baster to suck them out of the hole cut in the bottom of the bottle?

And then run to Mikes? I hear the clock ticking on that tangs life!

Thanks, Chris

Crows Ridge,
I use a brine shrimp net specifically designed for picking up the fry. I bought my net from coral beauty for $3 (I think). It works great.

Hatch usually takes 24 hours - maybe a bit more. Turn off the air and let it all settle a few minutes, if you see alot of swimmers they are ready. I'm sure you didn't decap.. so you should have alot of debris floating and sinking.. if you dip in a net you will catch a bunch of debris.

If you have airline running through the cap.... wait for all to settle then allow a little water to drain through the airline into a waste container to get rid of the debris on the bottom, then run the rest through a brine shrimp net (or coffee filter) stopping a little before the bottle is empty so you don't get the floating stuff. At this point gently rinse the bbs under running freshwater to remove bacteria or other nasties. Then invert the net into a container of new saltwater. HTH

What Vicky said works as well. My current settup doesn't allow for me to drain from the bottom of the hatchery!

Good luck hatching them. It's really not a difficult thing to do!

Okay, I checked this morning. Alot of crap on top!! At first, I thought it was a bad batch of eggs. But after a bit holding the bottle up to the sun, I could see a boatload of those little guys swimming around.:D

So, after work, I will rinse them and see if Mike is ready to "catch that tang"!

Thanks for the help!

Well, I dont know if I did it right or wrong. I got home, and the air line had come loose. Do they get the bubbler all the time?

I strained them through the BBS net, through the tube in the bottom of the bottle.

They are so small, I cant tell if they are swimming around, or just stirred by the moving of the bottle.

Are they supposed to settle in the bottom after rinsing?

I rinsed the net of orange in the tank and my fish went ballistic, but I still dont know if they are live still w/out air.

How soon do they need to be fed? I hope thay are well and I can get to Mikes. If hes not avail, I will start a new batch.

here are good instructions for hatching them.. for us we use tank water so skip the first 4 steps.

bbs hatching

for whats its worth I don't rince them I just move the light lower and they all swim to the bottom, then I skim the junk off the top (egg shells) and I dump the rest strait into the tank. the other way is to put the light at the bottom so all the BBS swim to the bottom, then use a turkey baster to suck them off the bottom.

if you are doing them for food, harvest after 18 hours.. newly hatched are the most nutritious.

Thanks! As soon as we can round up a trap. I think the LFS in Sumner rents or sells them.:confused:

They are swimming around in there after all though! Thats a good sign......................

They are not capable of eating for about 24 hours after they hatch. I'm guessing they would live for several days before they would actually die. But it's true that they are most nutritious right after they hatch... after the first 24 hours they are really only a package that holds whatever you have fed them. They are filter feeders and eat anything that their feet catch that is under 50 microns in size - I recommend phyto live or not.
