How To Choose Your Fish Tank Kit
Now that you have seen the best 20-gallon fish tank kits we could find, we hope you have a favorite. If not, then you may be wondering what you should consider when picking out a fish tank. There are several different things that will affect which tank is going to be right for you.
To start with, do you want to keep freshwater or saltwater fish? Most freshwater fish aren’t going to be as temperature sensitive as the tropical fish. If you choose to keep tropical fish then you’re going to need a heater for your tank. In this case, a tank that includes a heater is perfect for you.
Depending on the fish you want to keeps natural habitat you may need to change around a few things in your tank. For starters, do the fish you are getting live in calm water or flowing rivers. You’re going to need to have the right amount of water flow for your fish to swim around in.
If the fish you are choosing naturally live in a calm environment you will want to skip over strong filters. A filter that puts out a strong flow of water can overpower these fish leading to stress. This also goes for using a dull filter on a fish who is used to swimming against a current.
To have a happy fish you will also need to think about what they need in their environment. Most fish prefer to have plants whether they be real or fake. Fish naturally hide in these plants especially ones who are generally prey. Plants can ease a scarred fish decreasing stress.
If you like the look of real plants better then you are going to need an LED with enough power to make them grow. Not every LED is strong enough to promote the growth of real plants. To find out if the light is strong enough look-up what how much light the plant will need.
If you have chosen to go with a turtle or salamander then you will need to rethink your tank altogether. This is because these animals have different needs from a fish. The tank they go in will have to have heating lamps and above water spots to crawl on.
If your keeping a turtle you might even want to have a tougher tank then you do for normal fish. You will also need to keep in mind that turtle food and fish food don’t have the same nutrients. Lastly, You will want to make sure your turtle isn’t going to grow huge.
These are the our best 20-gallon fish tank kit reviews, there are quite a few perfect for both types of fish. Think about this guide and pick which tank fits your needs best. If you need a tropical tank then go for a heater kit, if you want a turtle then go for the reptile kit.
