Guppies in my tank

Based on the distinct patterns, body shapes, and coloration in the photos, I have Endler’s Livebearers (often called Endler’s Guppies) or very close Endler-Guppy hybrids.

Here is a breakdown of what you can see in the images:

1. The Male (Left in the second photo, top in the first)

• What to look for: This little guy is smaller, slender, and has the classic vivid, broken patterning on his body, along with a distinct double-sword or "forked" tail shape with colored margins.

• The Strain: He looks very much like a Tiger Endler or a Snake-chest Endler variant. The combination of black bars, yellow/orange accents, and that specific tail structure is a dead giveaway for Endler genetics rather than a standard fancy guppy.

2. The Female (Right in both photos)

• What to look for: She is slightly larger, rounder, and has a mostly translucent, silver-tan body with clear fins.

• The Clue: Notice the dark, round area near the back of her belly? That is her gravid spot, indicating she is pregnant (which is practically a permanent state for healthy female livebearers!).

Quick Tip

Because standard guppies and Endlers are so closely related, they will readily cross-breed. If you have them housed together, any fry they produce will be beautiful, energetic hybrids. They are incredibly hardy, active swimmers that absolutely light up under a tank light!
