Adding an aquarium to your household is a popular step to introducing basic animal care and responsibility for children, a way to get involved with a new hobby, or simply provide a means of relaxation. Let’s talk about freshwater fish for beginners that are relatively low-maintenance.
They are considered an easy-to-care-for, inexpensive, and low-maintenance pet option. However, be aware that this might not always be the case. And, running out to buy what looks best may be a disaster in the making.
There are many shapes and sizes of tanks and an incredible array of hardy species of fish in a variety of colors that are very cool to look at.
There also are saltwater and freshwater habitats, and various other species that can cohabit with your fish.
The bind many beginner fish keepers get into is not understanding the care of their tank, the types of fish they have, and mixing and matching species that shouldn’t be put together.
We are going to briefly explore low-maintenance fish options for you to choose from to ensure a happy, healthy aquarium environment.
Fish Buying 101
Before walking into your local pet stores or fish stores determined to walk out with everything you need to set up your perfect aquarium, first take a few things into consideration.
The biggest detail to pay attention to when getting started is tank size. Once filled with water, tanks weigh quite a bit and they need a sturdy place for them to sit. The larger they are, the more they will weigh.
You also don’t want to fill up the space you have with fish.
To keep fish healthy, they need space, especially if you have multiple species that like to school together. Even freshwater fish can be aggressive when they are too tightly packed together.
You want everyone to have enough room to swim away when needed.
For healthy fish, keep the general rule of thumb in mind: 1 inch of fish needs approximately one gallon.
For fish that grow larger, such as many goldfish, you may want to provide 2 gallons of water per one inch.
Overcrowding can result in diseases and fin shredding or picking.
You also want to take into account the various filters, lighting, gravel, aquarium plants, and decor that are needed in your fish tank.
