Maintain these water conditions for optimal health and vibrant colors
Rosy Phantom Tetra (Megalamphodus roseus) is a small, peaceful shoaling tetra for planted community aquariums. It works best as a group fish: keep six or more so the shoal feels secure and the soft rose body colour shows properly.
| Scientific name | Megalamphodus roseus |
|---|---|
| Adult size | About 3 cm |
| Group size | 6 or more |
| Minimum aquarium | 60 litres or larger |
| Water | 22-26C, pH 6.0-7.5 |
Use a mature aquarium with plants, open swimming room and gentle to moderate filtration. A darker background, wood or leaf-shadowed cover can help this tetra settle, but leave enough open mid-water space for the shoal to move together.
Feed fine flakes or micro pellets as the staple diet, with small frozen foods such as daphnia, cyclops or baby brine shrimp for variety. Offer small portions so the fish feed actively without food settling and spoiling the water.
Good companions include other peaceful tetras, rasboras, small Corydoras and calm community fish of similar size. Avoid aggressive fish, large predators and persistent fin nippers, especially in smaller aquariums.
