Asian bonytongues (arowana) reclassified

[MrTree]

Watching discovery channel in Reo Negro and seeing Cardinal tetra living in rather clear water, not as blackish as I expected..... Is this the reason why they are generally easier to keep than the Neon?

Is that "Built for the Kill"?

The neons are more difficult probably because of the neon disease.

most of the neon are rear by farming and Cardinal tetra are mostly harvested from the wild that might be another reason
