Evan Walsh –
The Blue Diamond Discus is stunning in my 120-liter aquarium. The metallic blue colour is vibrant and shines under proper lighting. I keep them in a group of six and they swim together peacefully. Water parameters are stable and I do weekly water changes. They look like a centerpiece and add a lot of visual appeal.
Sean Thomson –
I’ve had these fish for three months now. The colour is intense and consistent. They are active but calm, and they enjoy the group setting. I keep them in a well-maintained tank with warm water and good lighting. Very satisfied with the purchase.
Christian Ogden –
The fish arrived healthy and look beautiful. The blue colour is strong and they seem happy in the tank. I’m still adjusting the lighting, but they are settling in well. Would recommend for someone with a dedicated discus setup.
