A suitable tank

  • A 10 gallon tank, or bigger is suitable for this type of fish.
  • The water temperature should be maintained around 60 to 70 degrees fahrenheit.
  • Monitor the pH level and maintain it at 7.
  • Standard lighting fixtures used for aquariums can be used to provide light.
  • Don't put delicate plants in the aquarium. The fish like to dig and may even uproot the plants and feed on them. Either decorate the aquarium with fake plants, or grow plants with sturdy root systems that will be difficult for the fish to uproot.

Feeding your Black Moor

  • Feed Black Moor with sinking food pellets. Floating food pellets should be avoided. Because of poor eyesight they find it difficult to hunt for food if it's floating around in the tank.
  • Usual goldfish diet. You can also introduce the fish to tiny pieces of oranges, cucumbers, zucchini, blanched lettuce and spinach, peeled grapes and shelled peas. Sludge worms, bloodworms, daphnia, and brine shrimp can also be fed to these fish.
  • They are voracious eaters so be extra careful not to overfeed them, and don't feed foods that are too acidic or high in protein and sugar content.
