Notes:
Slowly, the number of fry for the latest angelfish spawning had decreased until they disappeared this afternoon (day 4). It seems that the mother is inexperienced at taking care of the fry, and often would cause the fry to fly off the leaf when she would aggressively chase the male off. The juvenile angelfish seemed to enjoy eating the fry, though.

When I vaccuumed the gravel during water changes, I would often notice a bunch of this uniform, short brown pieces about the size and shape of a "-" getting vaccuumed up. I finally figured out what it was today when I saw a shrimp exrete some poo: it was that same brown piece!
