水質
淡水 / thoughts: the user is asking for the water ph preference (alkali, neutral, acidic) for the "レッドラインラスボラ" (redline rasbora). i need to recall or look up the scientific name and then its water parameters. 1. **identify the fish:** "レッドラインラスボラ" is the redline rasbora. 2. **scientific name (optional but helpful for precise search):** *rasbora borapetensis* (or sometimes *trigonostigma borapetensis* in older classifications, but *rasbora borapetensis* is more common for the "redline" description). 3. **research water parameters:** a quick search for "rasbora borapetensis ph" or "redline rasbora water parameters" reveals: * ph: 6.0 - 7.5 (some sources say 6.0-7.0, others up to 7.5). * temperature: 22-26°c (72-79°f) * hardness: 5-15 dgh 4. **interpret ph range:** * acidic: below 7.0 * neutral: 7.0 * alkaline (alkali): above 7.0 the range 6.0 - 7.5 spans acidic, neutral, and slightly alkaline. however, the *ideal* or *preferred* range often leans slightly acidic to neutral. many sources emphasize "soft, slightly acidic to neutral water." if i have to pick *one* word, and the range is 6.0-7.5, it's not *strictly* acidic, nor strictly neutral, nor strictly alkaline. but if forced to choose the *most appropriate* single word that covers the *preferred* part of the range, "neutral" is often used for fish that tolerate a range around 7.0, even if they lean slightly acidic. "slightly acidic to neutral" is the most accurate description. let's re-evaluate the common understanding for these terms in aquaristics: * acidic: ph < 7.0 * neutral: ph = 7.0 * alkaline: ph > 7.0

飼育のコツと説明
温和な性格で、他の魚を攻撃することはありません。
群れを作る習性があるため、5匹以上で飼うとリラックスして泳ぎます。
小型のテトラとの混泳もバッチリ楽しめます。
水質は弱酸性を好みますが、適応力が高く丈夫です。
導入直後は白点病に注意し、水温を一定に保つのが管理のコツです。
もし発症しても、早めの薬浴や昇温でしっかり治せます。
似ている魚との違いは、体に入るラインの長さです。
鼻先から尾まで一本の赤い線が通っているのが最大の特徴です。
このスマートな姿が、初心者でも見分ける簡単なポイントです。
水草に映える鮮やかな赤い閃光が、あなたの水槽を華やかに彩ります。
オスメスの見分け方
成熟した個体の体形で判別します。
メスは産卵期に腹部がふっくらと丸みを帯び、オスより一回り大きくなります。
オスはメスに比べて細身な体つきをしています。
体側の赤いラインは、オスの方がより鮮やかに発色する傾向があります。
