Aquarium Fish

Emperor Tetra

The Emperor Tetra (Nematobrycon palmeri) does really well when kept in heavily planted aquariums. They may even breed on a regular basis if you have a small group of them. It's recommended to keep them in groups of 5 or more specimens. They are tetras so fin nipping may happen in the community aquarium. Keeping them in a small school should help focus their attentions on each other.

The Emperor Tetra gets to be about 1.5 inches (4.2 cm) and will adapt to a relatively wide range of water conditions regarding pH and dKH. They are tropical so a temp in the mid 70's F is recommended.
