The Easiest Aquarium Fish To Take Care Of
No aquarium fish is maintenance free - but some fish are easier to take care of than others. These are fish that are best for beginning aquatic hobbyists, as they are tougher in health and more forgiving of any mistakes the beginner is bound to make. The easiest aquarium fish to take care of are all freshwater fish. They are the Beta, the common goldfish and the plecostomus.
The Betta (also known as the Siamese Fighting Fish) is arguably one of the easiest aquarium fish to care for as well as being one of the most beautiful. He has a robust physical constitution and has been known to live in small bowls successfully, unlike other fish. He also produces less waste than goldfish.
However, he is a pugnacious fellow and often fights with other fish. He will kill another male Betta because he was bred to compete in fish fights. Female Bettas are much more social with other tropical fish, but they are drabber in color and have much shorter fins. They can eat the same foods as other tropical fish, with a particular attraction to bloodworms.
Many hobbyists argue that the common goldfish (and its close relation, the Comet Goldfish) are the easiest aquarium fish to take care of. They also are far more social than Bettas and come in brilliant colors. They do not require special diets and can tolerate just about any ornament you care to plop into a tank.
Egg-shaped goldfish that swim slowly, have bubble-eyes, no top fin or incredibly long fins are NOT considered easy to care for and also should not live in a tank with Common or Comet Goldfish. They swim so fast that the fan-tailed or egg-shaped goldfish will never be able to get their fair share of food.
The name "plecostomus" refers to a family of aquarium fish that has hundreds of varieties. Some are harder to take care of than others. But any plecostumus you find in your local pet shop among other tropical fish should be all right. They are bottom feeders like catfish or Chinese Algae Eaters and need their own kind of food.
However, they are hardy and tolerate swings in water chemistry more than most other kinds of aquarium fish. The only problem is that occasionally they outgrow the tank they are in. This happens unpredictably and it is not known why some grow so much bigger than others.
