The tropical fish were sold in Japan under the name of Columbia red fin. When I tried the beginning, I thought it was ferocious piranha, but I asked the clerk of the aquarium shop, the story is about a mild-mannered fish. Since face is similar to the piranha, I look scary. And began to shepherd along with a small fish, but it does not show the behavior that attack. Personality seems to be good-natured.
