Alternatively, I've been experimenting with the egg yolk (the yellow part) with pretty good results (very high survival rate). What you do is the following:
- Pinch off this much Egg yolk

))
- Hold the pinched egg underwater and slowly squish it side to side
- A cloud of egg yolk will appear and the larvae will feed on the cloud (as will the adults)
- You can use this to feed fish fry too (which was originally my primary use)
---CAUTION---do not overfeed otherwise it will pollute your water
How to prepare the egg (for those who don't know):
- Boil the egg (egg + cold water --> Heat till boiling --> Turn off heat--> Let sit for 10 mins in hot water)
- Take the egg out and let it cool till you can touch it
- Strip off shell and eat the egg white (or feed it to another person)
- Now you have the boiled egg yolk, which you can keep it for 1-2 weeks in the fridge in a small sealed container. Don't keep it for any longer, it won't stink but I'm thinking the bacterial levels+associated toxins are beginning to rise to a dangerous level. It kills some angel fry when I feed old egg to them.
