Sources & confidence (2 species)

These back the Neon Tetra and German Blue Ram figures used for this verdict. Each figure is read from the TankStocking species database (v2026.06); below is the care reference behind it and how confident we are in that data. Confidence reflects the source quality, not whether any pairing is safe. Full source list and the welfare model are on the methodology page.

  • German Blue Ram Mikrogeophagus ramirezi — Seriously Fish (seriouslyfish.com/species/mikrogeophagus-ramirezi) high confidence

Why

  • German Blue Ram needs ≥27°C but Neon Tetra needs ≤25°C — no shared safe temperature.
Why this doesn't work: German Blue Ram needs ≥27°C but Neon Tetra needs ≤25°C — no shared safe temperature. Rather than force it, keep Neon Tetra with tankmates the engine clears — see the engine-cleared alternatives below.
