If you’re seeking a freshwater fish that has bright color, a feisty personality, and a big size, the Red Terror Cichlid can be your ultimate fish or your worst nightmare. Also known as Cichlasoma festae, this cichlid gets its nickname “true red terror fish” because of its tough character and dominant posture in the aquarium.
This ultimate care guide will answer all: from Red Terror Cichlid size, appearance, diet, and tank mates to the difference between a true red terror and a Midas cichlid. We’ll even cover how they’re different from green terrors, and assist you in deciding whether or not this beautiful cichlid should be in your tank.
What Is a Red Terror Cichlid?
The Red Terror Cichlid, or Cichlasoma festae, is a big, territorial fish indigenous to the rivers of South America, particularly in Ecuador and northern Peru. It is a member of the cichlid species and is coveted for its dramatic reddish-orange color with black contrasting vertical stripes.
It has been said to be very intelligent, becoming attached to their caretakers and even recognizing them at mealtime. Even though they are stunning, their territorial and combative nature has led them to be called “terror.” However, if provided with proper conditions, they can be one of the most fulfilling fish to own.
In the Wild: Natural Habitat and Habits
In their natural range, Red Terror Cichlids live in fast-flowing streams and rivers with rocky substrate. The water is:
- Slightly acidic to neutral
- Warm throughout the year (75–84°F)
- Oxygen-rich as a result of the current
They are single or pair up, defending their area tenaciously, particularly when breeding. Their naturalistic nature provides much information as to what they require in captivity: room, form, and effective filtration.
