Description: An excellent choice for the smaller aquarium. Pygmy Cory is more torpedo shaped than other corys in the genus. The body is silver gray in color with a dark band running from the tip of the nose to the tail. A black spot is located at the base of the tail. Fins are clear. It lives in groups in nature so it's best to buy at least 6, preferably 10 or more. Females are fuller and larger, when viewed from above. Spawns in pairs or groups, having more than one male (2 males and one female) increases chances of spawning. Condition the group on a varied diet of live and frozen foods. When the females are visibly full of eggs perform a large (50-70%) water change with cooler water, and increase oxygenation and flow in the tank. Courtship behavior consists of the female nudging the midsection of the male in typical cory 'T' form. Eggs deposited around the tank, on glass and plants. Females release one egg at a time which is held between the anal fins where it is fertilized by the male. One female can lay up to 100 eggs during spawning. The eggs hatch in 3-5 days. Once the fry have used up their yolk sacs they should be fed on microworm or Artemia nauplii.
