Bloodfin tetra compatibility
Every pairing AquariumHQ has assessed for Bloodfin 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 Bloodfin 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 |
|---|---|---|
| temperature | 69 | 77% |
| zone competition | 30 | 33% |
| predation | 29 | 32% |
| breeding aggression | 27 | 30% |
| territory | 14 | 16% |
| ph | 8 | 9% |
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 |
|---|---|
| Workable | 34 |
| One animal at the edge of its range | 31 |
| Comfortable for both | 13 |
| Forced compromise — neither animal is where it wants to be | 11 |
| No overlap at all | 1 |
