You need to consider a number of points to be able to select the best fish tank for sale. For instance, you need to decide on the types and number of fish you want to keep. It will help you figure out how small your fish tank can be.
In case you're going for betta fish, you may get away with a fish tank containing 2 gallons of water. However, you will need a larger tank in case you're interested in keeping goldfish. A single goldfish would need a tank with a capacity of 10 gallons of water. Remember, a fish tank with almost 10 gallons of water is still considered small, but it all comes down to the types and number of fish you like.
Moreover, the best small fish tank is the one that suits the space you have to keep it. If you have very limited space, you just can't opt for large aquariums. Similarly, the overall weight of the tank matters as well. If you want a small tank that you can move around with ease, you may have to opt for something with a capacity of no more than 3 gallons. Even a small aquarium with 3 gallons of water may weigh up to 30 pounds or more depending on the weight of any ornaments, gravel, light, or filter you're using.
Even when buying a small tank, it is a good idea to consider what type of aquarium kit you're getting with it. Smaller units come with an efficient aquarium kit that has a built-in filter. The quality of the filter matters a lot because it provides your fish with the kind of environment they need to survive. An aquarium kit with filters is also important for water circulation, which in turn will help oxygenate the water. You should also ensure that the tanks you're buying are capable of handling good filters that provide better biological filtration as well as chemical filtration.
Along with considering the size you need, it is equally important to consider if you want to invest in a glass or acrylic aquarium. Both glass and acrylic aquariums are popular and have their own pros and cons. If you're looking for an aquarium that is difficult to scratch and quite sturdy at the same time, you may want to buy a glass tank. Another good thing is that glass aquariums are going to maintain their clarity for long. On the other hand, acrylic aquariums are much more lightweight than glass ones, and the added benefit of going for acrylic is that it's less susceptible to breaking or cracking.
Finally, you need to consider the size of the aquarium in relation to its weight. Again, you need to understand that even if you opt for a small glass tank, it is going to be much heavier than the acrylic tank of the same size. If you'd be moving it around quite often, be sure to go for a lighter tank.
Both large and small fish tanks are available, and how different people define small varies greatly. If it contains less than 10 gallons of water, you're going for fairly small fish tanks. For this size, you will have to consider the types of fish you can buy. Betta fish are quite popular but even they won't feel happy in a small one-gallon tank. If you're at least going for 5-gallon fish tanks, you will have more options and some are mentioned below.
In addition to these fish, you can also choose small critters for your small glass tank. Two popular options include the African dwarf frog and ghost shrimp.
Today, you can easily find fish tanks as per the space you have available and other unique preferences you may have. There are small glass aquariums with LED lights and a powerful aquarium kit. And there are aquariums with fancy design and rail light to keep a variety of fish. But, if you're buying a tank for the first time, you should avoid the misconception that going smaller is the better option.
If you think you can keep betta fish in a one-gallon tank, you're wrong. Most people think so because they're anabantids, which means they're capable of breathing air from the surface. Even then, they won't survive in less-than-ideal conditions. Moreover, a very small tank will have poor filtration, which means the water will get polluted quickly and ultimately putting your fish at risk.
If you're looking for the best starter fish tank without having to spend a lot of money, you should opt for a glass aquarium of at least 5 gallons. No matter what fish types you're choosing, you should give them enough space to swim. The design should also be roomy enough to support a filter and pump as well as a small heater.
Going for relatively larger tanks is the best thing to do even if you're looking for a starter tank because they're easier to maintain and will help turn you into a successful aquarium owner.
As mentioned already, many first-time aquarium owners are under the impression that maintaining a smaller tank is the easiest, but that's not true. Ideally, the tank should be large enough to help you use the related supplies. You will have to use the pump, filter, etc., and that needs space. Also bear in mind that the water chemistry will quickly go bad in a smaller tank as compared to a larger tank. For instance, ammonia level takes more time to rise in larger tanks, and you will have some time to react. That won't be the case with a smaller tank.
There's no denying the fact that having a small fish tank is much better than having no fish aquarium at all. But, it's also true that just because you're a first-time buyer, you need to stick to the small fish tank, as maintaining a larger one is easier and it provides ample space to use the filter, heater, and other equipment. If you're really interested in starting small, Marineland ML 90609 is probably the best bet. Go ahead and give it a shot!
