Bitterlings are carp-like in appearance, and are a great addition to either a backyard pond, or aquarium. Their bodies are generally silver to gold in color, and their dorsal and anal fins are highlighted in white. When mature, they will develope either a pink or blue hue at the base of their caudal fin.

The ideal aquarium is at least 30 gallons with many plants (either real or plastic), rocks with plenty of hiding places, gravel or sand is acceptable for a substrate.

Bitterlings are popular additions for ponds with large koi. They will feed upon parasites that infect the koi, especially anchor worms. They are very active fish that will also feed upon insect larvae and will help in controlling mosquitos in the water garden.

The Bitterlings will spawn into the mantle of a freshwater clam, where they will incubate. Provide a number of Bitterlings in the same aquarium to allow them to pair off. After the fry become waterborne, feed them newly hatched brine shrimp until large enough to accept other foods.

The Bitterling needs to be fed a variety of foods including vegetables as well as meaty foods. Feed a quality flake food as well as freeze dried, live, and frozen foods such as brine shrimp and bloodworms.
