These fish are vibrant and easy to care for. I kept them in a planted tank with other community fish, and they’ve been active and healthy for over six months. The tank looks beautiful with their bright yellow coloration.

They are peaceful and don’t stress other fish. I noticed they prefer cooler water, so I adjusted my heater settings. They’ve adapted well and are now part of my daily tank routine.

Great addition to a community tank. They swim together in schools and stay active even in a medium-sized aquarium. The plant compatibility is excellent, and they don’t compete for space.
