Lake Kutubu rainbow fish. Turquoise in colour. One of the most beautiful rainbows. The fish in the photo is a 2 year old male. These fish do best in groups of equal male to female ratios. Both sexes are very colourful but the males are brilliant when displaying for the females. They grow to about 4 inches long and require a aquarium minimum 3-4 feet long. They love to school together and are a gentle community fish. 8$ each or 6x for 30$ Some are 1 1/2 inches and can be sexed
