I've got asolene spixi snail eggs again and would love to get a few babies out of them this time as I'm down to only 2 old adults left. I don't know if they're fertile. How can I tell? Last time I think the eggs got eaten by fish. I've moved the dwarf gourami and swordtail out of the tank. The only current fishy inhabitants are neon tetras and bristlenose plecos. Will either eat the eggs? Do I need to remove either or should I move the eggs? I think I've read spixi eggs need extra good filtration? Anything else I need to know? Help, please!
