2/28/15 (Saturday) - There haven't been many deaths until today. This morning I found about 20 fry (too many) or more at the bottom of the tank tangled in decaying plants or fuzzy stuff growing over them. I have been siphoning everyday because I think I may have overfed with micro worms, but they've only started dying last night/this morning. I can't tell if they are even eating the worms, like I usually can with other spawns. There are many microorganisms in the tank so they might be eating those and letting the worms rot at the bottom. Or they could be starving, which may be why many are dying. I can hatch BBS if I want, but if even micro worms are too big, then I can't imagine them eating it.
Also, do you count how old the fry are from when the eggs are fertilized, when the eggs hatch, or when they start free swimming?
