Aquarium Fish Species care guide
Pisces (tropical freshwater community fish) · Characidae, Poeciliidae, Osphronemidae, etc.
Aquarium Fish Species (Pisces (tropical freshwater community fish)) is an aquarium animal. It belongs to the Characidae, Poeciliidae, Osphronemidae, etc. family. It is native to Neon tetra: upper Amazon (W Brazil, E Peru, SE Colombia); guppy: NE South America & the southern Caribbean; betta: central Thailand to the Malay Peninsula. Water temperature: Species-dependent, typically 22°C – 28°C (neon tetra 21–25°C, guppy 17–28°C, betta 22–30°C). pH: Species-dependent: neons do best in soft, acidic water (about 4 – 7.5); guppies in hard, alkaline water (7 – 8.5). Care difficulty: Easy.
How do you care for Aquarium Fish Species?
| Light | Gentle lighting with plant shade |
|---|---|
| CO₂ | Maintain CO₂ < 30 ppm to prevent hypoxia |
| Temperature | Species-dependent, typically 22°C – 28°C (neon tetra 21–25°C, guppy 17–28°C, betta 22–30°C) |
| pH | Species-dependent: neons do best in soft, acidic water (about 4 – 7.5); guppies in hard, alkaline water (7 – 8.5) |
| Placement | Midwater (tetras, guppies), upper water (betta) |
| Growth | Guppies are livebearers and breed readily; tetras and bettas need dedicated breeding setups |
| Difficulty | Easy |
| Family | Characidae, Poeciliidae, Osphronemidae, etc. |
How do you trim and propagate Aquarium Fish Species?
Feed 1–2 times daily (consumed in 2 mins); siphon uneaten food. Only add fish to a cycled tank (ammonia and nitrite undetectable).
What problems affect Aquarium Fish Species?
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.
How do you fix Aquarium Fish Species problems?
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.
Where does Aquarium Fish Species come from?
Neon tetra: upper Amazon (W Brazil, E Peru, SE Colombia); guppy: NE South America & the southern Caribbean; betta: central Thailand to the Malay Peninsula
What should you know before buying Aquarium Fish Species?
Never release aquarium fish — guppies and bettas have established feral populations outside their range. Copper-based medications are lethal to shrimp and snails.
