⚠ 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:

Acidity/pH Gap0.3 pH difference

Angelfish thrives in pH 6-7.5, while Electric Yellow Cichlid needs pH 7.8-8.6.

⚔️ Do Angelfish and Electric Yellow Cichlid 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 Angelfish, 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

Both species are closely matched in physical dimensions, with Angelfish growing to 6.0 inches and Electric Yellow Cichlid reaching 5.0 inches. This size balance ensures neither species holds a physical dominance advantage.

Frequently Asked Questions: Angelfish & Electric Yellow Cichlid Compatibility

Are Angelfish and Electric Yellow Cichlid good tank mates?

Water acidity (pH) parameters clash. Angelfish prefers a pH of 6-7.5, while Electric Yellow Cichlid requires a pH of 7.8-8.6. There is no overlapping safe pH range.

Can you put Angelfish and Electric Yellow Cichlid 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 Angelfish, making them completely incompatible cohabitants.

What water temperature and pH parameters do Angelfish and Electric Yellow Cichlid need?

Both species require compatible parameters. Angelfish needs a temperature of 75°F to 82°F and a pH of 6.0 to 7.5. Meanwhile, Electric Yellow Cichlid needs a temperature of 75°F to 82°F and a pH of 7.8 to 8.6. Shared overlap range: 75°F–82°F temperature and No safe pH overlap overlap.

What is the minimum combined tank volume required to house Angelfish and Electric Yellow Cichlid?

To successfully house both species together, a baseline of 50 gallons is required. However, because the setup includes territorial behavior from Angelfish (semi-aggressive) and 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.
