5 Best Fish For Pets of 2021

Guide to Fish For Pets

It’s a great idea to have a pet fish! They’re cute, entertaining and they can really be a lot of fun. However, there are many things you need to know about keeping a fish as a pet.

First, you need some supplies. You’ll need a fish tank, of course, and all the things that go along with it: gravel, a filter, food, and a water conditioner. In addition, you’re going to want to have some fun decor for your fish tank. There are many options! You can add plants or rocks or stones or little toys. The important thing is that you know exactly what kind of pet fish you want before beginning this process.

Once your supplies have been acquired, it’s time to set up your tank! The first step is gravel rinsing. This means taking out an old container-like appliance and filling it with gravel from the bag of aquarium gravel. Then you run water over the gravel until it runs clean.

Next, set up your filter system. Fill it with water from your fish tank and turn it on to get the water flowing through the filter system. Lastly, place your tank where you want it, fill it with fresh tap water, add conditioner and let it sit for a few hours so that the chemicals can settle into the water properly. Afterward, add decor before placing in any fish!

Here’s a list of typically suggested types of pets for beginners

Tetra – commonly suggested for beginners due to their hardiness and ease of care. These fish are slightly more difficult to breed

Corydoras – these fish like to be in schools and will help clean your tank by eating leftover food and algae.

Mollies – good for beginners because they like the same water conditions as most tropical community fish (75-82F). They can live up to 5 years or more!

Swordtails – also a relatively hardy fish that is easy to breed. Good for beginners as long as you have a compatible school of at least 6-8 of them, as they prefer it that way.

Silver Dollars – these larger fish need tanks with strong filters but otherwise are very hearty and easy to take care of.

Goldfish – surprisingly easy to care for, and can live happily in a smaller bowl by themselves.
