Bubble Eye Black Moor Goldfish – Detailed Care Instructions

Bubble Eye Black Moor Goldfish

Bubble Eye Black Moor Goldfish is often added to collections as a color contrast to a colorful aquarium. In this article, Aquatic 247 will help you show you methods to care for this fish.

What is Bubble Eye Black Moor Goldfish?

The Bubble Eye Black Moor Goldfish pedigree can be traced back to the Spectacled Moor, a descendant of Japan’s most popular Goldfish breed, the two-tailed Wakin. The scientific name is Carassius auratus auratus var.

Selective breeding has produced popular goldfish breeds, including Ranchus, Orandas, and Fantails. These fish are never discovered in the wild unless they are released by aquarium owners.

Besides, Black Goldfish With Bubble Eyes have a big orb of fluid beneath each of their eyes. These protrusions, located beneath a fragile flap of skin, may impair your fish’s ability to swim and forage. These bulges will wrinkle and bend with your fish’s movement, as is typical of this type of goldfish.

Care guide Bubble Eye Black Moor Goldfish?

Bubbleeye goldfish environment and care demand extra attention and consideration. Here are some impacts to consider.

Tank size

First and foremost, you’ll need at least a 10-gallon tank. However, we recommend starting with 20 gallons, if possible. While they are not the strongest swimmers, the large tank size will be greatly appreciated.

If your tank is only for display, choose a tank that is somewhat taller than it is wide since taller plants, such as Vallisneria, can be grown in a taller tank, which also provides a bigger viewing area.

Water quality

Bubble Eye Black Moor Goldfish require water that is somewhat neutral, clean, and balanced. Water changes should be performed regularly. Bubbleeye goldfish are particularly susceptible to low water conditions.

We recommend replacing a fourth of the water per week. This will maintain relatively low levels of ammonia and nitrate.

Here are some water parameters to stick to:

  • Water temperature: 60–80°F
  • pH: 6.0–8.0
  • Ammonia: 0
  • Nitrites: 0
  • Nitrates: 20 ppm
  • General hardness: 130–200 ppm (dGH 7–11)
  • Carbonate hardness: 89–142 ppm (dKH 5–8)


Black Bubble Eye Goldfish are shortsightedness since tend to blunder around an aquarium. If the aquarium has any sharp edges, the eye structure may be cut. When this occurs, body fluids seep out and the telescopic eye structure collapses. The lens does not mend itself or reinflate; instead, it dips into the eye socket, surrounded by extra skin.

Tank substrate

Use plain medium-sized gravel as the substrate. Make sure the gravel is quite smooth. These fish frequently browse on the tank’s bottom (even though they are not traditional bottom feeders), therefore, the bags may occasionally come into contact with the substrate.

Fish tank

Finding a good tankmate for Bubble Eye Goldfish is difficult since their eye sacs are susceptible to aggressive fish.

Furthermore, slow swimming makes it difficult for them to consume food and water regularly. Fast swimming fish will compete for food, leaving nothing for the Black Bubble Eye Goldfish.

They perform exceptionally well in groups of the same species. However, if you intend to construct a community tank, select fish with flaws similar to the Black Goldfish With Bubble Eyes. Here are some suitable tankmates to consider.

Diet and feeding of Bubble Eyed Black Goldfish

Feeding bubble eyes requires patience. Because Black Goldfish With Bubble Eyes have visual and swimming problems, it takes them longer to eat than most other fish. This is a reason we advocate keeping them exclusively with slower, more attractive goldfish or other species with bubble eyes.

When choosing a food for Bug Eyed Black Goldfish, you should want to go with slightly higher protein levels, from 33 to 38 percent, than a regular. Fancy varieties require more energy to swim regularly, so a few more calories can help them stay more active.

Fact: Bubble Eye Black Moor Goldfish cannot be overfed! Goldfish eat slowly, compared to other fish species, because they have rudimentary stomachs. They shove as much food as they can into their mouths, then carefully chew and swallow before taking another bite.

Breeding of Bubble Eyed Black Goldfish

Bug Eyed Black Goldfish reproduce very quickly if the conditions are right. The appropriate initial temperature is 60 degrees. Then, increasing the temperature gradually each day (68 – 74 degrees), the male will begin to pursue the female around.

After spawning, these fish will eat their eggs immediately. Therefore, you should set up a separate tank to raise your fry. Eggs can take 4 to 7 days to hatch.

You can feed the fry infusoria and other powdered foods until they are ready to consume scales. Babies don’t have the iconic eye bags. They will begin to develop at 6 months of age.

In conclusion

Bubble Eye Black Moor Goldfish have many unique characteristics, you need to be very careful when setting up their habitat. If you can ensure some of the conditions we mentioned above, we recommend keeping this fish to increase the uniqueness of your aquarium.
