I move the wood the eggs are on on the 3rd day and put them in a 4x2x2 with a canister filter. I also put a mesh over the inlet so they can't be sucked up into the filter. 50% of the fry normally die but that's just what happens. When my pair breed I normally have around 2000 free swimmers after 5-6 days. But you need to feed 5 times a day or they will just eat each other. Let me know how you get on.
