Yes, fish are easy to take care of because they don't need to be walked like dogs. They're less time consuming than most pets. Fish are also easy to take care of because they can be left at home for a couple hours and you don't have to watch over them. They will just "keep on swimming". Just make sure to clean your fish tank every 2 weeks by changing the filter, changing the water (only take out 50%-70% of water because it leaves benefical bacteria that helps your fish. I recommend using a helpful invention called the 'GravelVac'. Make sure to refill the tank with clean tap water), cleaning the gravel (again, you can also do this with the GravelVac, it's amazing) and make sure to feed your fish! Don't worry, it doesn't take as much work as you think!

Fish are small and don't take up much space. Fish can be put in tanks or bowls, so if you think about it, bowls don't take up much space at all. Just make sure your tank or bowl is at least 5 gallons big, unless you are getting a very tiny, small fish. If fish don't have much room to swim and live, they will get really stressed out and can die. It's just like if a human were to have to live in a small cardboard box.
No, fish don't cost much, all you need to do is to buy the necessary equipment. Equipment that is needed for a fish includes a fish tank, fish food suitable for your fish, some nice decorations to make your fish happy, fish gravel for the ground, and last, the fish. Make sure to buy one from your local, trusted pet store such as petco or petsmart. :)
In conclusion, fish are awesome starter pets because they are easy to take care of, they don't take up much space, and don't cost much. Personally, I have a fish, and I love my fish. It was my first pet ever and she is still alive. It's also fun taking care of a fish because it teaches you responsibility and they're just overall fun to watch. Hopefully you will consider having a fish as your first pet. Thank you for reading!
