Well, I ditched the last eggs - I guess they just weren't meant to be.
I've not had another albino spawn yet, although I did a water change yesterday and rinsed the filter (in tank water) so there is a much improved water flow and now the male is all excited and hassling his chosen female again - bless 'em.
But... my one of my peppereds has spawned twice - well she too ate the first lot (silly corys), but she's hidden some under some plants and stuck a half dozen to the glass.
Decided I'm letting nature take it course here as they are only young still. If/when either of them start laying bigger amounts of eggs I'll try again to hatch them =)
Totally unplanned I managed to end up with 1 male, 2 females each of albino corys, peppered corys, zebra danios and leopard danios!
