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.
In addition to the regular two tone color on the body there is also an all black color morph. See the image below.

Check with your local laws before getting a Piranha. Some municipalities have banned the sale of the Piranha.
Can be considered a good tetra for the freshwater fish beginner due to its hardy and peaceful nature.
Red Belly Pacu
The Pacu gets way too big for most home aquariums and is then sometimes released into local waterways. Ugh. Do not release fish into your local water ways!
