Shared water parameters
- No shared temperature window.
- pH both tolerate: 6–7
- Hardness both tolerate: 2–10 dGH
- Recommended combined tank: 32 gallons or larger
Risks and things to watch
Temperature conflict
The comfortable ranges barely meet. Running one species at the edge of its range for months is a slow-burn health problem, not an instant one — which is why it often goes unnoticed.
Both occupy the bottom zone
Competition for space and food is higher when two species share the same layer. Increase footprint rather than height.
Group requirements
Compatibility is not only about the two species getting along — each still needs its own social setup met inside the same tank.
- German Blue Ram — no group requirement; single specimens are fine.
- Panda Corydoras — minimum group of 6. Budget tank space for the whole shoal, not one fish.
Frequently asked questions
Can german blue ram and panda corydoras live together?
Not recommended. We do not recommend housing German Blue Ram with Panda Corydoras. The conflicts below are structural — they are not solved by a bigger tank or more plants. Choose a different tank mate instead.
What size tank do german blue ram and panda corydoras need together?
Plan for at least 32 gallons. German Blue Ram alone needs 20 gallons and Panda Corydoras needs 20, but combined stocking needs headroom for filtration and swimming space, not just volume.
What temperature suits both species?
There is no shared comfortable range: German Blue Ram needs 78–85°F and Panda Corydoras needs 68–77°F. That alone rules the pairing out.
What pH works for both?
Aim for pH 6–7, which sits inside both species' comfortable range.
Will german blue ram eat panda corydoras?
Unlikely. At 2.5″ versus 2.0″ the size gap is not large enough for predation, though fry and juveniles are never safe in a community tank.
How should the tank be arranged?
Use plants, wood and rock to break sight lines, keep open swimming space along the front, and add the more territorial species last so it cannot claim the whole tank before the other settles in.
