Red-eye tetra compatibility
Every pairing AquariumHQ has assessed for Red-eye tetra, derived from stored behavioural and environmental traits. Each verdict links to the reasoning behind it — including where the evidence runs out.
The species record is on the Red-eye tetra page. Any pairing not listed here can be assessed on demand with the compatibility checker.
What decides this species' pairings
Counted across every assessment above — the dimensions that actually raise concerns for this animal, rather than the ones a care sheet would list.
| Dimension | Pairings raising it | Share |
|---|---|---|
| zone competition | 30 | 33% |
| breeding aggression | 27 | 30% |
| predation | 23 | 26% |
| temperature | 20 | 22% |
| territory | 14 | 16% |
| ph | 7 | 8% |
Environmental compromise
Whether a shared temperature, pH and hardness band exists is a necessary condition, not evidence that it suits both animals. This counts how good the overlap actually is.
| Overlap quality | Pairings |
|---|---|
| Comfortable for both | 40 |
| Workable | 29 |
| One animal at the edge of its range | 10 |
| Forced compromise — neither animal is where it wants to be | 7 |
| Narrow — little margin | 4 |
