⚠ 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:
Cardinal Tetra thrives in pH 4.6-6.2, while Siamese Algae Eater needs pH 6.5-7.5.
Behavioral & Environmental Compatibility
⚔️ Do Cardinal Tetra and Siamese Algae Eater Fight?
Environmental or structural requirements between these species clash too heavily to allow cohabitation. Water acidity (pH) parameters clash. Siamese Algae Eater prefers a pH of 6.5-7.5, while Cardinal Tetra requires a pH of 4.6-6.2. 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 Cardinal Tetra occupies the mid layer, while the Siamese Algae Eater occupies the bottom layer. This separation of swimming zones naturally minimizes direct interactions and reduces competition during feeding times.
📏 Size Difference & Predation Threat
There is a moderate size difference. The Siamese Algae Eater (6.0 inches) is noticeably larger than the Cardinal Tetra (2.0 inches). While not an immediate predation threat under normal circumstances, ensure the smaller specimens are not small enough to be eaten and have plenty of shelter.

Can you put Cardinal Tetra and Siamese Algae Eater in the same tank together?
Environmental or structural requirements between these species clash too heavily to allow cohabitation. Water acidity (pH) parameters clash. Siamese Algae Eater prefers a pH of 6.5-7.5, while Cardinal Tetra requires a pH of 4.6-6.2. There is no overlapping safe pH range.
What water temperature and pH parameters do Cardinal Tetra and Siamese Algae Eater need?
Both species require compatible parameters. Cardinal Tetra needs a temperature of 73°F to 81°F and a pH of 4.6 to 6.2. Meanwhile, Siamese Algae Eater needs a temperature of 75°F to 80°F and a pH of 6.5 to 7.5. Shared overlap range: 75°F–80°F temperature and No safe pH overlap overlap.
What is the minimum combined tank volume required to house Cardinal Tetra and Siamese Algae Eater?
To successfully house both species together, the minimum baseline capacity is 30 gallons. Because both Cardinal Tetra and Siamese Algae Eater are peaceful community species, no extra territorial buffer volume is required.
Do Cardinal Tetra and Siamese Algae Eater occupy the same swimming layer?
These species occupy different vertical zones. Cardinal Tetra prefers the mid layer, while Siamese Algae Eater commands the bottom zone. This natural spatial stratification creates an effective biological barrier, preventing direct face-to-face boundary friction and reducing territorial encounters.
