Fry Hatching
Ringer's, as was mentioned, is nothing more than a salt solution.
I stole the following recipie from:
http://www.csuchico.edu/biol/Stockroom/recipies.shtml
Rat Ringers
0.9% NaCl
0.24% CaCl2
0.042% KCl
0.02% NaHCO3
0.1% Dextrose
(if requested)
My only addition to the comments on killifish egg hatching is that I've
had the best success with incubating the eggs in small batches in very
small (2 oz sauce cups) containers - and that I've had most success with
'dry incubating' [putting eggs on top of freshly boiled-cooled wet peat
moss, then removing most of the moisture before incubating in the dark].
There are a few species who I have not been able to 'dry incubate' (F.
chrysoteus - very large eggs, for example). But my major problem is
always mold.
My objection to the multi-compartment method is that I suspect that
there are times when one or two compartments needs good cleaning out,
but that cannot be done because the rest are filled.
If I do water incubate, I use very fresh tap water that I just
dechlorinate and add acriflavine solution, leaving it in and sealing the
egg in container. When I've had one egg hatch with other eggs not yet
hatched, I have a problem removing the fry without prematurely 'popping'
the eggs, so I try to place eggs of same development together or
incubate singly.
Uh, in fact, I've had so much success these past few months that I do
have some fishes to find homes for now, so feel free to contact me.
