These fish are very calm and add a vibrant red color to the tank. I kept them in a group of ten with other tetras and they stayed peaceful. The red color became more intense after I added dark gravel.

Great for a community tank. They don’t stress other fish and are easy to care for. I noticed the males show more color when they’re together, which is a nice sight.

I’m happy with the color and temperament. They thrive in a cooler setup without a heater, which saves on equipment costs. The group behavior is natural and entertaining.

They’re hardy and don’t require much attention. I feed them once daily with flake and a bit of frozen food. The red hue is noticeable and stays consistent.
