One Fish, Two Fish, Red Fish, Goldfish: Black Moor


The black moor is velvety black. Its skin’s texture being similar to the “leather skinned” koi. Its eye traits are usually described as “dragon-eyes” or “telescopes,” but to distinguish this creature from any other black telescoped-eye fish (also called moors), just look at its bronze belly, which tends to slowly spread upwards as time passes. Although bacterial infections and diseases can cause a goldfish’s eyes to stick out (“pop eye”) don’t be so quick to mistake its odd eyes as a symptom of illness. Despite its poor vision, the black moor typically grows to be strong and healthy––like mine––and hobbyists believe that it should be put with fish that carry similar disadvantages, like the bubble or celestial eye goldfish.


When building a home for the black moor, it’s best to avoid putting sharp decorations or ornaments inside the tank, as these details can result in cuts on the fish’s protruding eyes. But if you’d still like to spruce up the black moor’s abode, get real plants to create a more natural scene. Using live freshwater plants is helpful to the aquarium’s filtration cycle, and common varieties are softer than their plastic counterparts.

However, a larger problem arises with the addition of adding plants to the tank. Like all goldfish, the black moor enjoys bottom-feeding–– sucking endlessly at the tank’s gravel or sand substrate––to find food that may have dropped from the previous feeding. As the fish bottom-feeds, it will likely run into plants, begin to unearth them and eat their roots. But there is a way to hinder them, in the hope of preserving your beloved herbage. If you put its roots into a jar and cover and bury them with gravel, your plants may stand a chance.


If you still don’t have a fish collection, now is the time to start one! Already a budding fish-enthusiast? Now you’ve been introduced to another cool breed of fish––the black moor––so think about adding one to your tank.

As with my previous post, I will gladly answer any questions left in the comments box.
