Question about pulling the spawn.

When I've done this I have relocated the pair and left the eggs in the tank.  It's worked for me.  I thought it was the normal way to do.  But I've read elsewhere about raising the fry in jars.  I don't get it.  Why is a smaller water volume better than a larger water volume?  The smallest tank I breed in is a 20 high.  The largest right now is a 40.

   Some folks prefer the gallon jars, but my preference is a 2 1/2 gal tank. With a smaller vessel, you can perform a larger volume of water change using less water..ie...20 gal with 50% change = 10 gal's...with a 2 1/2 it's only a little over a gallon. Hatching in a smaller vessel, the fry are kept in closer proximity to foods introduced. Cleaning and maintaining is easier too, plus the parents aren't moved and can go on their merry way. 
  I'm not a fan of the 'hatching' jars either, but some folks have great success...same with the external breeding boxes. I have a gallon external box that's nice for popping cory or BN fry into, in a pinch...but usually go with my old standby....the 2 1/2.....plus it's hard to get your hands inside a gallon jar to do anything..LOL...with the 2 1/2...easy peasy to do what you need..slates fit in there nicely too..
   It's all what you're comfortable with, I guess...

For now, if I raise without parents I'll do it my way.  WC is easy for me and my water is cheap.  I over feed BBS but with a large water volume all I ever need to do is vacuum the bottom and keep the sponges well squeezed.

I like the tetra 5.5 gallon tanks.  Like Jon said, gives you a bit of room to work, but keeps the fry in a confined space.  Also, I can buy the 5.5 gallons tanks much cheaper than the smaller 2.5 gallon ones.
