IME, venting is the most accurate way of determining the sex of cichlids. Post a few pics of its vent.

From the picture, it looks like a beautiful Jack Dempsey! Determining the gender can be tricky, but typically:

• Males have brighter and more intense colors, especially blues and greens, and longer, more pointed dorsal and anal fins.
• Females are usually less colorful and have more rounded fins. Some females may also have a black spot on the dorsal fin.

Based on what I can see, if the colors are bright and the fins are sharp, there's a good chance it's a male. However, without seeing a few more angles or behaviors (like pairing or nesting), it's hard to say for sure.


Try posting a few more pics from different angles, and if possible, a few close-ups of its vent for a more accurate determination.

How big is your fish? It looks maybe 3 inches or so?

Many fish, cichlids especially, look female when small...It looks kinda girlie. Dorsal (top) fin looks short & rounded; anal (bottom) fin looks longer but not as long as male's get...when adult.

This is a better side on pic. I'm voting male based on long pointy dorsal & anal fins...& size. He still has some growing to do but looks male. Sometimes young fish can look female but not the other way around.
