The tinfoil barb (Barbonymus schwanenfeldii) is a very large freshwater fish from Cyprinidae family. It can be up to 14 inches (35 cm) long. Quite often the juveniles are sold on the market and nobody tells about how large the fish becomes as an adult one and as a result, the fish quickly overgrows any tank of a common aquarist and then requires a really spacious tank.
The Odessa barb (Pethia padamya) is a small, bright and active fish. Unfortunately, it is less spread than other barb species. Earlier it was considered that the Odessa barb was one of Puntius ticto coloring variations (which natural coloring doesn’t have wide red stripe along its body peculiar for this species). This version is quite prevailing in literature on aquarium husbandry. In 2008 Pethia padamya was described as a separate species.
