Male Angelfish vs. Female Angelfish: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 18, 2024
Male angelfish often have larger, more pronounced dorsal and anal fins compared to female angelfish, which typically have rounder bodies for egg-laying.

Key Differences

Male angelfish are distinguished by their larger and more angular dorsal and anal fins, which are used for display and territorial defense. In contrast, female angelfish tend to have softer, more rounded fins, reflecting their primary role in reproduction.
The body shape of male angelfish is typically more streamlined and pointed, aiding in agility and territorial defense. Female angelfish, however, often exhibit a fuller, rounder body shape, an adaptation for carrying eggs.
In the realm of coloration, male angelfish can exhibit more vibrant and varied colors, a trait linked to attracting mates. Female angelfish, while also colorful, often have more subdued hues, which might aid in camouflage during the vulnerable egg-laying period.
Behavioral differences are notable: male angelfish are more territorial and aggressive, especially during mating seasons. Female angelfish, on the other hand, focus more on finding suitable locations for laying eggs and often exhibit nurturing behaviors.
During breeding, the male angelfish's role is to fertilize the eggs after the female angelfish lays them. The female angelfish is responsible for selecting a safe surface for egg-laying and often guards the eggs post-fertilization.
