Ok, just had my first experience with fry! My guppy has given birth and I managed to get a little over 20 into the breeder net. Any others are dead or not near the floating plants. I've been sprinkling in crumbled up spirulina flakes as I don't have any fry specific food. I'm heading to my LFS tomorrow night to get stuff but I'm not sure what they stock so I'll need lots of options if they won't be able to survive on flakes. What do I absolutely NEED for them?
