⚠ 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:
Electric Yellow Cichlid thrives in pH 7.8-8.6, while Harlequin Rasbora needs pH 6-6.8.
⚔️ Do Electric Yellow Cichlid and Harlequin Rasbora Fight?
Behavioral analysis indicates a severe compatibility clash. The Electric Yellow Cichlid is known for highly territorial and aggressive behaviors. In a shared environment, it is highly likely to harass, injure, or stress the more peaceful Harlequin Rasbora, making them completely incompatible cohabitants.
🍽️ 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. Both species reside in the mid layer. Feeding them simultaneously in different corners of the tank is highly recommended to distribute food and prevent any resource competition in their shared vertical zone.
📏 Size Difference & Predation Threat
There is a moderate size difference. The Electric Yellow Cichlid (5.0 inches) is noticeably larger than the Harlequin Rasbora (1.8 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.

Frequently Asked Questions: Electric Yellow Cichlid & Harlequin Rasbora Compatibility
Are Electric Yellow Cichlid and Harlequin Rasbora good tank mates?
Water acidity (pH) parameters clash. Harlequin Rasbora prefers a pH of 6-6.8, while Electric Yellow Cichlid requires a pH of 7.8-8.6. There is no overlapping safe pH range.
Can you put Electric Yellow Cichlid and Harlequin Rasbora in the same tank together?
Behavioral analysis indicates a severe compatibility clash. The Electric Yellow Cichlid is known for highly territorial and aggressive behaviors. In a shared environment, it is highly likely to harass, injure, or stress the more peaceful Harlequin Rasbora, making them completely incompatible cohabitants.
What water temperature and pH parameters do Electric Yellow Cichlid and Harlequin Rasbora need?
Both species require compatible parameters. Electric Yellow Cichlid needs a temperature of 75°F to 82°F and a pH of 7.8 to 8.6. Meanwhile, Harlequin Rasbora needs a temperature of 73°F to 80°F and a pH of 6.0 to 6.8. Shared overlap range: 75°F–80°F temperature and No safe pH overlap overlap.
What is the minimum combined tank volume required to house Electric Yellow Cichlid and Harlequin Rasbora?
To successfully house both species together, a baseline of 50 gallons is required. However, because the setup includes territorial behavior from Electric Yellow Cichlid (aggressive), we recommend an adjusted minimum tank volume of at least 70 gallons (adding a 20-gallon safety buffer) to establish separate visual boundaries and minimize stress.
