The Zaire Blue Frontosas are beautiful and peaceful. After a few weeks, they settled into their tank and started exploring the plants. I’ve kept them with other cichlids, but only after adding plenty of hiding spots. They don’t show aggression as long as there’s enough space and cover.

They arrived healthy and have been active since setup. The color is vibrant and they move slowly, which is perfect for a calm aquarium. I recommend a tank of at least 55 gallons to give them room to grow.

I bought this pair for my 75-gallon tank. They’ve adapted well and are now part of the main group. The blue color stands out and they seem content with the environment. Good investment for a visually striking fish.
