ベタ稚魚が全滅しました。3週間目に何が起きたのか

【ベタ繁殖シリーズ・第3話/完結編】 凪アクアです。 今回はベタ繁殖シリーズの第3話、そして完結編をお届けします。 第1話で無事にふ化し、第2話で3日目の壁を越えた稚魚たちが、3週間目に全員☆になってしまいました。 これは「失敗の報告動画」ではなく、ベタ繁殖の全貌を学べる教材としてお届けします。 最善を尽くしましたが、結果としてこうなりました。 これからベタ繁殖に挑戦する方への参考になればと思って、起きたこと・推測される原因・注意点を、できるだけ丁寧に記録しています。 至らなかった部分もあったと思います。 それも含めて、正直にお話ししています。 ▼ シリーズをまとめて見るならこちら 📺 ベタ繁殖・育成記録    • ベタ繁殖・育成記録|凪アクア   ▼ 🐟 チャンネル登録はこちら    / @凪アクア   ▼ SNS X(Twitter):https://x.com/naginagiaqua ───────────────── 本動画の音声はVOICEVOX(四国めたん)を使用しています。 https://voicevox.hiroshiba.jp/ BGM:Mr. Sunny Face - Wayne Jones(YouTube音声ライブラリ) ───────────────── English summary: This is the third and final episode of my betta breeding series. Sadly, all of my betta fry passed away around 3 weeks old. I share what I observed, including signs of "brine shrimp crash" (overfeeding caused digestive failure), and what I would do differently next time. I did my best, but this was the result. I hope this honest record helps anyone who is starting their own betta breeding journey. #熱帯魚 #アクアリウム #凪アクア #ベタ #ベタ繁殖
