Rosy Tetra (Megalamphodus rosaceus)
The Rosy Tetra is a peaceful and elegant South American shoaling fish, loved for its soft pink to rose-coloured body, translucent fins and graceful swimming behaviour. Mature males often develop brighter colour and longer dorsal and anal fins, while females are usually fuller-bodied. Also widely sold as Hyphessobrycon rosaceus, this species makes a beautiful addition to mature planted community aquariums, especially when kept in a proper group with subdued lighting, dark décor and calm tank mates.

I’ve had a group of Rosy Tetras for three months now. They’re very peaceful and add a soft, elegant look to the tank. The males have developed nice pink hues and longer fins. I keep them with other peaceful community fish and they don’t compete for space. The tank looks much more natural with them in it.

The fish are active but not flashy. They swim in a coordinated group and look beautiful in a planted tank. I noticed the males became more vibrant after a few weeks. I like the subtle pink tones and the way their fins move in the water.

Great addition to my community tank. They don’t stress other fish and are easy to care for. I feed them daily with flakes and occasional live foods. The colouring is soft and natural, and they seem happy in the dim lighting I provide.
