Black Moor Goldfish Tank Mates In Mixed Aquarium

Most of us love goldfish, many however have no idea how many different breeds of goldfish there are and most probably don’t really care or take time to research. They just like to see some pretty goldfish swimming about in an aquarium or hopefully not one of those little round fish bowls. As with any other fish bowl may be all right for temporary use or for the occasional isolation of a fish that may be ill, but generally, that would be like putting the little guy in prison. Most fish don’t necessarily need a great deal of room, but they do need room to swim about. As we mentioned above, there are many different breeds of goldfish such as the bubble eyes, the comet, fantail and so on. Most are not terribly expensive and generally don´t need a lot of fish keeping knowledge.

One goldfish that really stands out is the black moor or telescope goldfish because of its protruding eyes. If you’re a purist you can call them Carassius Auratus, but most people settle for calling them black moors or simply moors. These are chubby little fellows with flowing fantails and while nominally black, many catch a flash of golden light as they swim about (although to naked eye, their coat appears more like velvet). We can’t expect them to remain black forever, because as they grow older their colors may change in different ways. They may develop orange spots on their underbelly, or gold and sometimes may become rather splotchy. Being hardy as are most goldfish, these fish are fairly easy of maintenance. They remain fairly small and may live up to some twenty-five years.

Non-aggressive, moors usually do well when in a group of other goldfish. Because of their different color characteristics, black moors are popular all over the world and additional benefit is that they enjoy an outdoor pond as they can survive the extremely cold weather. When thinking what fish are compatible with black moor goldfish, as we mentioned, they are non-aggressive and should only be kept in a tank with other non-aggressive goldfish. The characteristic protruding eyes, while interesting, provide poor eyesight for the black moor and competing for food with other tank mates can be a real problem (eyes are also quite vulnerable to injury and infection). Some of the other hardy goldfish may not make the best tank companions, especially in a pond, because most breeds are more competitive when it comes to feeding. Goldfish that pair well with the black moors might be celestial goldfish and the bubble-eye goldfish. Loaches also do well with them, but with these, you should keep at least two adding more bottom for them to dig about which may mean a larger tank for you to buy. Another possibility is the Plecos. Plecos offer the advantage of eating algae, thus helping keep the algae in check. However note that only the rubbernose or bristlenose plecos should be brought in because common plecos sometimes have the habit of sucking the protective slime coat from goldfish.

Anyway for black moor companion the best would be to ask a knowledgeable person at the aquarium store to help you pick other goldfish who share the black moor’s characteristics, namely slow swimmers that get along well with your them. Finding good tank mates isn’t as difficult as that may sound. There are many varieties of pet fish that share poor vision, slow swimming and non-aggressive behavior for you to choose from. While many pet stores or even discounts stores often have a goldfish section, the employees may know less than you do about the product they’re selling. You’re much better off to go to an aquarium store that specializes in fish and water life of all kinds. Such stores sell only water-related fish, sometimes frogs, etc. as well as plants and equipment. Usually, the owner and employees will be much more knowledgeable about the breeds of fish, the plant life and everything else connected with your having an enjoyable aquarium.

SIZE OF TANK WITH mixed setup

Most would recommend a black moor fish tank that holds at least thirty gallons when possible although you would be fine with a 10 gallon for start until they grow older and bigger. A fine gravel bottom with some hardy plants is recommended. All goldfish like to poke about in the bottom and after they’ve scattered sand and gravel about on the leaves of less hardy plants, you may have to replant. When thinking about feeding almost any dry or live fish food will be quite suitable for these little round fish. Of course, many black moors are tiny when brought home and a ten-gallon tank may suffice for some time.

Since they are very slow swimmers, other goldfish, while not really aggressive, swim so much more quickly and see so much better that they often devour all the available food before the poor fish can get a portion. However, even a larger tank does not mean you should fill it with too many fish. Even a thirty-gallon tank shouldn’t have more than two or three goldfish. Four tops. One word of caution, these are pretty messy, and, like all goldfish, they produce a good amount of ammonia.You’ll need a fairly good-sized filter. Some suggest that even a twenty or thirty-gallon tank will do better with a filter designed for a forty-gallon tank. The extra currents in the water are an unexpected bonus for your fish who’ll enjoy the movement of the water. Remember, most goldfish get along quite well together; it’s just a matter of them not waiting around for the slower fish to share dinner. That’s very common in the world of animals whether they live on the land or in the water. Some, more cautious, suggest not having any but black moor goldfish in your tank, adding perhaps a couple of snails for additional variety and color. Too many fish in a tank can easily and unintentionally bruise the bulging eyes of a fish and that could quickly prove to be fatal.

In the end, keeping an attractive and interesting aquarium may not be as easy as we might wish, but it can be well worth the extra care when properly inhabited by the right number of healthy fishes and other black moor tank mates.


  1. My ex had a black moor, just by himself. I loved that little guy. He was a PIG though. Before we started dating she had him with some other fish and I guess because he outgrew them, he ended up killing them and eating them. One of the other kinds were guppies so you can see how easily the size issue can happen there. I think as long as they are with fish their own size, they do just fine.

  2. I purchased two goldfish last October. I had no clue what I was doing nor the type of fish that I purchased. They where both very small when I got them and I place them in a 3 gallon aquarium that I had set up weeks before. The tank was on the kitchen counter so I was always around the fish and they were always ready to eat. I soon found out that these small gold fish got bigger quickly. After researching I found that the fish was a Black Moor and a Ryukin. I found that the tank was to small and purchased a 20 gallon tank. (Knowing that it too would need to be replace soon). What really surprised me was how much the Black Moor cared for the Ryukin. Day and night it stayed at the Ryukin side. When I had to separate the Moor because of an injury it swim in the corner of the quarantine tank trying non-stop to reach the Ryukin. No matter what I tried it would face the 20 gallon tank and swim against the wall of the quarantine tank in an attempt to re joint the Ryukin. After three day of this I put the Moor back with the Ryukin and if a fish feel joy these two was completely over came by it. The Ryukin at first eat way more food then the Moor. I would put food throughout the tank to ensure the Moor had time to find enough food but over time the Ryukin seem to understand the Moor had move trouble finding food and would move away to allow the Moor to find food.

    The Ryukin had swim blatter issues. On March 12, 2018, I started to have blatter issues and no matter what I tried it died two days late. Throughout these terrible days the Moor stayed at the Ryukin side refusing to eat or move away. I wake on the 14th to find the Ryukin had died and the Moor on the bottom of the tank under the Ryukin. I removed the Ryukin and the Moor had no reaction. After a week the Moor was still not eating, staying near the bottom of the tank. I purchased two additional goldfish in hope to help the Moor. After placing the new fish with the Moor he started to move around the tank and soon was engaged and eating with the new fish.

    I have now purchased an 80 gallon tank and the three fish seem to be doing well. I am looking a female Black Moor around 5” to join Buster. He doing very well but I think at thinks he miss the Ryukin.

    If you looking a fish that is friendly but a bit clumsy the Black Moor is your Goldfish. Just understand that they don’t see well so keep things out of the tank that they might injury themselves on. I had to remove everything from the tank but my live plants to ensure Buster would not hurt himself. He has hung himself up on top of the power head, injuryed his eye on the hard scrape and countless other situations where I had to help it out of. But its a great fish. It knows me and will swim to the front of the tank to watch me. I have moved my hand up and down the face of the tank and it will follow it. Understand too that from my experience these fish had some form of emotions and from what I have seem becomes very attached to they tank mates. Please give them a tank big enough to explore but safe.

    Sorry for being so long but I wanted you to know more about a Black Moor Goldfish.
