In the wild, \u003cem\u003eParacheirodon innesi\u003c\/em\u003e lives among leaf litter, submerged roots, fallen branches, and dense marginal vegetation. These waters are often shaded by forest canopy, which means fish experience dim light, tannin staining, and soft, slightly acidic conditions.

That said, a larger aquarium of 60-90 litres gives a much better result because the fish school more confidently, water quality is easier to maintain, and you have room for more natural aquascaping. If customers ask “\u003cstrong\u003eneon tetra how many\u003c\/strong\u003e can I keep?”, the answer depends on volume, filtration, and tank mates, but this species looks best in groups of 10 or more once the aquarium is mature.\u003c\/p\u003e\n\u003ch3\u003eTank Size Requirements\u003c\/h3\u003e\n\u003cp\u003eFor a 6 fish starter group, 40 litres is acceptable, but for a full display school, 60 litres or more is strongly recommended. A longer tank is better than a tall one because these fish use the middle water column and appreciate horizontal swimming space. If you are planning a \u003cstrong\u003ediamond head neon tetra school of 6\u003c\/strong\u003e, think of it as the beginning of a larger school rather than the final stocking level.\u003c\/p\u003e\n\u003ch3\u003eWater Parameters\u003c\/h3\u003e\n\u003cp\u003eThe ideal \u003cstrong\u003eneon tetra temperature\u003c\/strong\u003e is 22-25°C, though the full \u003cstrong\u003eParacheirodon innesi temperature range\u003c\/strong\u003e is 20-26°C. If you are checking the best \u003cstrong\u003etemperature for neon tetra\u003c\/strong\u003e, aim for the middle of that range for long-term consistency. Preferred \u003cstrong\u003eneon tetra pH range\u003c\/strong\u003e is 5.5-7.0, though they can adapt to 7.5 if changes are gradual. Keep \u003cstrong\u003eneon tetra water hardness\u003c\/strong\u003e low, ideally 1-10 dGH, because softer water supports better colour and easier acclimation.
