The Penguin Tetra (Thayeria boehlkei) comes from the upper Amazon River Basin and feeds on small worms, insects and crustaceans in the small streams in which it is found. They need to be kept in a small school of 5 or more and with similar sized tank mates.
The Penguin Tetra gets to be about 1.2 inches (3 cm). Food wise, you can use a good pellet food like NLS (New Life Specturm) or Hikari to form the main portion of their diet. The 1 mm sized pellets work well when they are adult size. Flake foods or crushed flakes may work better with smaller fish.

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!
