The Black Moor Goldfish is one of several varieties of Carassius auratus auratus. All goldfish are members of the carp group and are generally quite hardy. A 30 gallon or larger tank with a fine gravel bottom and hardy, cold water plants is recommended. Goldfish are diggers and will scatter the fine sand onto leaves, injuring thin and less hardy plants.

Can you keep goldfish and tropical fish together?

I strongly advise against keeping goldfish and tropical fish together for several reasons. First, goldfish tend to thrive at sub-tropical temperatures, which means about 68 to 72 degrees Fahrenheit. This is not to say that 75-degree water will kill the goldfish. It’s just that the lower temperatures are healthier for them. Cooler water holds more oxygen, which larger goldfish require for good health. Second, goldfish tend to be much more massive than tropical fish. As they grow, they can easily eat more than the tropicals. The latter may end up […] Read more »

Goldfish (Carassius Auratus)

Goldfish are diggers and will scatter the fine sand onto leaves, injuring thin and less hardy plants, particularly fine-leaved varieties. They often dig in the gravel and can uproot plants or damage their stems. Plants grafted onto rocks or wood (e.g. anubias, java fern) are good choices. Fancy goldfish, need a tank free of active or aggressive fishes, they require optimum water conditions to prevent fin damage and deterioration.

Goldfish: Maximum Size and Lifespan

It is a myth that a goldfish will grow only to the size of their tank. If a goldfish is kept in a small tank, fed only a small amount once daily, and the water changed regularly, it will grow only very slowly and may live for several years, reaching a maximum size of maybe 3 to 4 inches (8 to 10 centimeters). It is true that the growth of a goldfish may be somewhat stunted in a small tank – a high nitrate level is known to stunt growth […] Read more »

Goldfish: Swim Bladder Problems.

The fish are unable to maintain an upright position when still and may float head-down, on their side, or upside down. The fish may sit on the bottom of the aquarium and struggle to swim to the surface, or may hang at the surface and be unable to swim down. Weakness and lethargy and a resulting loss of balance can also be caused if the fish is ill with another disease, so check for other symptoms. Swim Bladder Problems Symptoms: Fish can control their position in the water with the […] Read more »
