  Some of you may not have noticed, but male and female electric blue acara have slightly different sizes. The males tend to grow faster to a somewhat larger size—some fish often reach 7 inches—while the females are smaller, at around 5 inches.

  In my tank, the male electric blue acara always steals the show with its sparkling blue, especially during the breeding season when the colors are even more striking. Plus, the male has a red spot on his throat.

  While beautiful, the electric blue acara female has a softer, more subtle hue. I have noticed that they do well with a balanced diet. FYI, the electric blue acara is omnivorous!

  Well, I think this is the most striking difference between electric blue acara male vs female. The male has elongated, pointed dorsal and anal fins. It gives a sleek impression when he swims in the tank. On the other hand, the female stays classy with shorter, rounded fins. You might be mesmerized by its delicate look.

  Watching the sex difference is the easiest way to tell the difference. In terms of sexual maturity, male electric blue acara will show off beautiful colors and pointed fins as they grow up.

  Besides, the female electric blue acara focuses on function. She matures with the ability to produce eggs. Yeah, the female is the real main character during breeding.

• Breeding Behavior

  Breeding time is a team effort for electric blue acaras. The male stays busy fertilizing and guarding the eggs. Of course, females have an important role here. They will remove the eggs and carefully place them in a clean spot at the bottom of the tank. Both work together to guard the eggs until they successfully hatch.
