The Odessa Barb (Puntius padamya) is a metallic fish, with coppery dorsal side and a lighter colored belly. They have two black spots on each side, and males are usually more colorful than females. Odessa barbs are generally peaceful, and can be kept in most community tanks with similar sized fish.
Barbs are popular aquarium fish from the Cyprinidae family, one of the largest in freshwater that also includes other popular fish like Danios and Tetras. Most of the barbs available to aquarists are from the genus Puntius although several others are also found, including Barbus, Garra, Barbonymus, Barilius and others.
The large Puntius genus ranges from tiny 1" fish to larger species that reach a foot or more in length. Most of those sold for aquariums reach around 3-5 inches in length. This group includes some of the most popular freshwater aquarium fish: Tiger Barbs, Cherry Barbs, Gold Barbs, Rosy Barbs and others. This genus found throughout Asia. These fish are schooling and should be kept in groups of at least five or more fish. Keeping fewer fish will increase their individual aggressiveness, leading to their notorious reputation as semi-aggressive fin-nippers.
I have 7 of these fish in my 36 gallon and they definitely keep things moving. They are very active, playful fish and spend their time in all areas of the tank. When they are comfortable in a tank with good quality water they have fantastic, bright red coloring down the sides with dark gray/almost black along the back and belly. Their eyes contrast as neon orange. Under the right conditions their coloring is fantastic.
They definitely enjoy the company of their own kind and will chase and race each other around the tank, or join as a group and play in the filter outlet. When I only had 4 they definitely nipped the fins of my angels. Since I upped their numbers to 7 they seem happier and keep to themselves (for the most part). They can be naughty littly buggers but not nearly as badly as some of the other barb varieties.
