A tank of 4 ft long or longer is recommended for a goldfish as some may reach up to a length of 12 inches. Most people think a 10 gallon tank will be big enough for a full-grown goldfish, but they are wrong. Some goldfish are even kept in ponds with koi fish. Goldfish are not meant for small aquariums.


A hood is recommended as it aids in helping your fish stay in the tank. Also, the hood keeps debris or dust from falling into the tank.


For Lighting: Full spectrum lighting – T5 is recommended.


Every fish and tank is different, so it is important to know what you’re dealing with. Some fish love a lot of current and others love no current at all like bettas. Some fish tanks are tiny and some are huge. Knowing what you have, or what you are going to have will help aid you in deciding which filter to go with.

Tank Items

Silk plants, live plants, and decorative ornaments may be put into a Black Moor’s tank. But stay away from ornaments that are used as hides. As you see, these Black Moor’s have very big bulging eyes which can be harmed if trying to squeeze into a small hiding place which are usually found in decorative tank decor.  If choosing to use live plants, be aware that Black moor’s love to eat plants and may destroy your plants in doing so. Some goldfish keepers buy inexpensive floating plants (i.e. Anacharis) just for this purpose. If choosing to use fake plants, try to use mainly silk fake plants which are smoother for the fish’s skin. Some fake plants are very rough and can scrape the sides of your fish’s skin if rubbed the wrong way. This is just something to take into consideration when going plant shopping. Hides really aren’t needed in a goldfish’s enclosure.


Since the Black Moor is an omnivore. It should be fed a varied diet consisting ideally of sinking pellets, occasional vegetation and bloodworm/daphnia etc.


The Black Moor is a type of goldfish. Knowing Goldfish poop 24/7, you are going to want to go with a substrate that is easy to clean and is safe for your goldfish. Most people prefer to use sand rather than gravel due to the impaction gravel may cause if ingested. However, if gravel is the way you want to go, make sure to use very fine gravel that will not harm your goldfish if ingested. River stones are another option you may choose to go with due to the fact that river stones are bigger than the goldfish’s mouth so therefore it can not be ingested. But have in mind, cleaning will be a lot harder since you will have to manually pick up each river stone to clean the bottom of the tank.
