The Koi Angels are a beautiful addition to my 55-gallon tank. Their colors are vivid and they swim with grace. I’ve noticed they become more active in the evening. I do have to keep them in a larger tank due to their territorial behavior.
Cameron Knox –
Great fish with a unique look. They’ve been in my tank for three months and are still very active. I’ve had to adjust my tank layout to give them space, but it’s worth it for the visual impact.
Nicola Alsop –
The fish look impressive at first, but they’ve been a bit aggressive with my smaller tetras. I’m now keeping them in a separate tank to avoid conflict.

I was impressed by how fast they adapted to the tank. Their orange and black patterns stand out even in a busy aquarium. I recommend giving them plenty of space and a stable environment.
