Standard Goldfish (Carassius auratus)

Are goldfish easy to take care of? This is one of the first questions I get from beginners in fish-keeping. The truth is that there are many varieties of goldfish.

Most fancy goldfish require more work to maintain but the Standard Goldfish can be a great choice for beginners. Goldfish are not only fun to watch but they quickly become sociable with their owners, making them a great choice for beginners.  

A standard goldfish has a lifespan of about 20 years. Gold Comet fish, Common, Shunbunkin, and Fantail Goldfish all make for good tropical fish for beginners.

The standard goldfish are bright, inexpensive, and easy to maintain fish that are easy to take care of. They are cold-water fish that prefer a temperature between 65° – 72° F.

Whatever type of goldfish you choose, you should ensure that you have about 20 gallons of water per fish.

This type of goldfish has a length of 1 to 2 inches and can grow up to 6 inches in some cases. It has two sets of paired fins and 3 single fins. It does not have any scales on the head but has exceptionally large eyes.

The fish come in red, orange, blueish-grey, brown, yellow, white, and black colors.

Betta Fish

The Betta fish has a reputation of being the easiest fish to take care of but may need a few upgrades to have a long and happy life.

Betta fish need about a five-gallon tank minimum with a filter and heater. They should be kept at 78 to 82 degrees Fahrenheit (26 to 28 degrees Celsius).

It is advisable to have a bigger volume of water to make it easier for your heater to keep a constant temperature. Invest in a quality thermometer to ensure the water is always at the right temperature.

The fish comes with long, delicate fins and overlapping scales, which come in vibrant colors like red, green, and blue. The fins are prone to be knocked about by quick flowing water thus you need the right size filter and turn the flow down.

You also need to use decor that is betta specific since their fins are easily torn on sharp decor items. They have a length of about 3 to 4 inches when they are grown.
