观赏鱼品种养护指南
Pisces (tropical freshwater community fish) · Characidae, Poeciliidae, Osphronemidae, etc.
观赏鱼品种 (Pisces (tropical freshwater community fish)) 是一种水族生物。 隶属于Characidae, Poeciliidae, Osphronemidae, etc.科。 原产于Neon tetra: upper Amazon (W Brazil, E Peru, SE Colombia); guppy: NE South America & the southern Caribbean; betta: central Thailand to the Malay Peninsula。 生长需要带有水草遮蔽的柔和光照光照。 适宜水温：Species-dependent, typically 22°C – 28°C (neon tetra 21–25°C, guppy 17–28°C, betta 22–30°C)。 pH范围：Species-dependent: neons do best in soft, acidic water (about 4 – 7.5); guppies in hard, alkaline water (7 – 8.5)。 养护难度：Easy。 生长速度：guppies are livebearers and breed readily; tetras and bettas need dedicated breeding setups。
如何养护观赏鱼品种？
| 光照 | 带有水草遮蔽的柔和光照 |
|---|---|
| CO₂ | 保持 CO₂ < 30 ppm 以防止鱼只缺氧 |

| pH | Species-dependent: neons do best in soft, acidic water (about 4 – 7.5); guppies in hard, alkaline water (7 – 8.5) |
| 造景位置 | Midwater (tetras, guppies), upper water (betta) |
| 生长速度 | Guppies are livebearers and breed readily; tetras and bettas need dedicated breeding setups |
| 养护难度 | Easy |
| 科属 | Characidae, Poeciliidae, Osphronemidae, etc. |
如何修剪与繁殖观赏鱼品种？
Feed 1–2 times daily (consumed in 2 mins); siphon uneaten food. Only add fish to a cycled tank (ammonia and nitrite undetectable).
观赏鱼品种有哪些常见问题？
White spot (Ich): 0.5–1 mm white specks on body and fins, cycle 3–6 days at 24–26°C; gasping and sudden deaths in a new tank from ammonia/nitrite before the biofilter is established; neons with white patches swimming apart (possible neon tetra disease); weak, short-lived guppies from inbred mass-produced stock.
如何解决观赏鱼品种的常见问题？
Treat Ich repeatedly (at least 3–5 treatments until losses stop): salt at 4–5 g/L for 7–10 days or formalin per label; remove carbon and aerate well. Heat is not a cure — warm water only speeds the parasite's cycle so treatments must be more frequent, and 29–30°C is above the neon tetra's range; salt also harms plants and scaleless fish. Quarantine new fish for 30 days; in a new tank test weekly, change water, feed less and stock slowly.

购买观赏鱼品种前需要了解什么？
Never release aquarium fish — guppies and bettas have established feral populations outside their range. Copper-based medications are lethal to shrimp and snails.
