Here’s a new thick, chunky recipe for storing semi-annual eggs in this case, F. filamentosus (FIL).
Use a generous quantity of peat moss.
Add a small handful of java moss.
Introduce a pair or trio of FIL into a 12 inch tank (water also helps).
Add a small quantity of paramecium.
Allow the adult fish to spawn for 2-4 weeks.
Remove peat and wring out in a fine net until it’s the consistency of “not-so-sloppy mud”. Forget the smoking tobacco theory!
Place peat and eggs in a plastic container and store at a temperature of 21C (70F) for 6-8 weeks.
Dump peat into a tank or settled water at 23C (74F). Wait 3-4 hours and watch VAST quantities of paramecium (and other protozoans) emerge, along with plenty of FIL fry … complete with a ready-made food source.
