⚠ Physiological Mismatch Report
Our stocking engine calculations indicate that putting these two species in the same tank causes acute physiological strain. Below are the calculated parameters that violate safe cohabitation ranges:
Knight Goby Fish thrives in pH 7-8.5, while Rummynose Tetra needs pH 5.5-6.8.
Behavioral & Environmental Compatibility
⚔️ Do Knight Goby Fish and Rummynose Tetra Fight?
Environmental or structural requirements between these species clash too heavily to allow cohabitation. Water acidity (pH) parameters clash. Rummynose Tetra prefers a pH of 5.5-6.8, while Knight Goby Fish requires a pH of 7-8.5. There is no overlapping safe pH range.
🍽️ Swimming Layers & Feeding Competition
To satisfy their dietary requirements, offer a varied feeding schedule. Sinking pellets or wafers are ideal for bottom dwellers, while floating flakes or micro-granules support mid and top dwellers. The Knight Goby Fish occupies the bottom layer, while the Rummynose Tetra occupies the mid layer. This separation of swimming zones naturally minimizes direct interactions and reduces competition during feeding times.
📏 Size Difference & Predation Threat
Both species are closely matched in physical dimensions, with Knight Goby Fish growing to 3.5 inches and Rummynose Tetra reaching 2.0 inches. This size balance ensures neither species holds a physical dominance advantage.

Frequently Asked Questions
Are Knight Goby Fish and Rummynose Tetra good tank mates?
Water acidity (pH) parameters clash. Rummynose Tetra prefers a pH of 5.5-6.8, while Knight Goby Fish requires a pH of 7-8.5. There is no overlapping safe pH range.
Can you put Knight Goby Fish and Rummynose Tetra in the same tank together?
Environmental or structural requirements between these species clash too heavily to allow cohabitation. Water acidity (pH) parameters clash. Rummynose Tetra prefers a pH of 5.5-6.8, while Knight Goby Fish requires a pH of 7-8.5. There is no overlapping safe pH range.
What water temperature and pH parameters do Knight Goby Fish and Rummynose Tetra need?
Both species require compatible parameters. Knight Goby Fish needs a temperature of 72°F to 82°F and a pH of 7.0 to 8.5. Meanwhile, Rummynose Tetra needs a temperature of 75°F to 84°F and a pH of 5.5 to 6.8. Shared overlap range: 75°F–82°F temperature and No safe pH overlap overlap.
What is the minimum combined tank volume required to house Knight Goby Fish and Rummynose Tetra?
To successfully house both species together, a baseline of 30 gallons is required. However, because the setup includes territorial behavior from Knight Goby Fish (semi-aggressive), we recommend an adjusted minimum tank volume of at least 40 gallons (adding a 10-gallon safety buffer) to establish separate visual boundaries and minimize stress.
Do Knight Goby Fish and Rummynose Tetra occupy the same swimming layer?
These species occupy different vertical zones. Knight Goby Fish prefers the bottom layer, while Rummynose Tetra commands the mid zone. This natural spatial stratification creates an effective biological barrier, preventing direct face-to-face boundary friction and reducing territorial encounters.
