    7. FREESEA Betta AquariumFREESEA

     

    The FREESEA Betta Aquarium is a 1.4-gallon aquarium made of sturdy plastic. This aquarium is seamless and has rounded edges.

    This aquarium has three viewing sides and a darkened back with a hidden filtration compartment. It Includes a plastic hood with built-in LED lighting, filtration system, and two plastic plants. The plastic divider that hides the filter can be removed for more tank space. It is available with white or black accents.

    The filtration system on this aquarium may be too strong for bettas, fry, and shrimp, and may require replacement to something weaker. This kit does not include a heater. The LED lights are very bright and not dimmable, so they may be too bright for some fish. This aquarium is too small to use as a permanent solution for a betta fish, but it could be used for a period of time.

    • Rounded edges and hidden compartment for filtration system
    • Includes hood with built-in LED lights

    8. Penn Plax Betta Fish Tank AquariumPenn Plax Betta Fish Tank

    This kit includes a clear plastic hood with built-in LED light, an internal filter, and a black raised base. The filter can be placed in different parts of the tank based on your preference. It includes a filter cartridge with the purchase. The LED light is only moderately bright and is easily operated with an on/off switch. This tank is small enough to be used in a small space like a desk or shelf.

    This kit does not include a heater. This aquarium is too small for long-term use for a betta but could be used for a while until you are able to get a larger tank set up. The manufacturer for this tank does not produce the replacement filter cartridges, so you will need to purchase an appropriately-sized cartridge from another manufacturer. This LED light cannot be replaced, and this item is a premium price for the size of the tank.

    • Rounded edges
    • Includes hood with built-in LED light

    9. Hygger Horizon 8 Gallon LED Glass AquariumHygger Horizon

     

    The Hygger Horizon 8-Gallon LED Glass Aquarium is a beautiful glass tank with a curved front and built-in faux rocks. This tank measures 8 gallons but only actually holds around 6 gallons of water due to the faux rocks.

    This aquarium kit includes a filtration system hidden in a compartment, a waterfall-look filter output, and a removable LED light that can be extended up to 19 inches. The LED light has white, blue, and red lights built into it and has three lighting modes. It has a controller in the electrical cord of the light that allows you control over the modes, brightness, and time the light stays on. The filter is a 2-stage filtration system that can be run with as little as 2 gallons of water in the tank.

    The filtration system is specific to this tank, so it can’t easily be customized to your preference. The filter is too strong for small fish, fry, shrimp, and may be too high flow for your betta’s liking. There is not a lid with this tank, so you may have to find another brand or custom hood to fit if needed. The faux rocks cannot be removed.

    Pros
    • Unique shape and built-in faux rocks
    • Includes filter for hidden compartment
    • Waterfall-look filter output
    • LED light is removable and includes options for modes, brightness, and time
    • Filter can be run with as little as 2 gallons of water in the tank

    • Filter is too strong for some fish
    • No lid or hood included
    • Faux rocks cannot be removed
    • 8-gallon tank but only actually holds 6 gallons of water
    • Doesn’t include a heater

    10. Aqueon Betta Bowl AquariumAqueon Betta Fish Tank

     

    The Aqueon Betta Bowl Aquarium is the least comprehensive kit on the list and is not appropriate for keeping a betta for more than a few days at the most. It only holds 0.5 gallons of water and is made from clear plastic with lid color options of black or blue.

    This kit only includes the most basic equipment, including an easy-open feeding window in the lid, a plastic plant, gravel, and samples of fish food and water conditioner. There is no space for a filter in this tank, although you may be able to fit a small airstone or sponge filter. This kit includes a plastic divider to house two bettas side by side, but this is not advisable due to the limited space and the potential for stress to both fish.

    This tank is in no way an appropriate permanent home for a betta fish, but it is a great option for moving, travel, vet visits, or short-term keeping while preparing or cleaning a larger tank. It does not include a heater, but a flat betta heater would likely fit in this, although it will take up swimming space. It also doesn’t have much space for plants or other enrichment items.

    Pros
    • Lid options of black or blue
    • Easy-open feeding window
    • Includes a plastic plant and gravel
    • Good option for very short-term keeping
    Cons
    • Least comprehensive kit
    • Too small for long-term keeping
    • Does not include a heater
    • Little space for plants or enrichment items
    • Too small for a filter
    • Housing two bettas in this is not advisable

    Buyer’s Guide

    What to Consider When Choosing the Right Betta Tank for Your Needs:
    • Size: It’s generally recommended to not permanently keep bettas in a tank smaller than 5 gallons. This will help prevent stress to the fish in the long run and will help maintain its health.
    • Space: Available tank space doesn’t just allow for your betta to have swimming space, but it also allows you to add plants and enrichment items to the tank. Plants are especially important for bettas because they provide feelings of safety and security. Happy fish are healthy fish!
    • Material: The two main materials that tanks are made from are glass and plastic, usually acrylic. Glass has the benefits of being sturdy, having little flexibility, lasting a long time, and being extremely difficult to scratch. Acrylic has the benefits of being shatterproof, lightweight, clearer than glass, and able to be formed into many unique, seamless shapes. However, glass isn’t shatterproof and is extremely heavy, while acrylic is easy to scratch and too flexible for some shapes and sizes of tanks. Knowing the shape and weight of tank your space will allow can help guide you in choosing between these two options.
    • Tankmates: Usually, betta fish are recommended as solitary fish. However, some bettas do well in community tanks with short-finned, peaceful fish. The most important aspect of keeping a betta in a community tank is ensuring there is plenty of space for everyone to coexist peacefully and without stress. A tank with a betta and other fish as tankmates should be 10 gallons at minimum. Hiding places, plants, and a backup plan in case your betta decides to act up are all necessary when considering this.
    What to Look for When Choosing a Betta Tank:
    • Filtration: Bettas are known for preferring slow moving water and will be stressed by filtration that is too strong or creates too strong of a current in the tank. Choosing a tank that either has a low-flow filter or has the option to replace the included filter with a filter of your choice is the way to go when it comes to providing filtration for a betta fish.
    • Durability: High-quality products are going to last longer than cheaply-made products. Choosing a tank with good reviews and sturdy materials will save you money in the long run.
    • Ease of Access: Obviously having the option to quickly and easily open your tank for feeding or brief maintenance is preferable, but the most important aspect of ease of access in your tank is how easily and efficiently you will be able to clean and maintain your tank. If you can’t fit your hand into the filter slot or don’t have a tool to help you clean it, then you’re less likely to adequately clean that area. If you can’t easily and quickly reach into your tank to unclog a filter or move items if necessary, then it may be frustrating and take you more time to get simple tasks done.
    • Warranty: Finding a betta tank with a warranty is key to saving you time and money. Some warranties will cover shipping damage but not leaks. Some warranties may cover a few months while others may cover a year or more. Finding a warranty that covers the item you are purchasing in its entirety, including things like filters, will come in handy if you end up with a damaged or defective product. Even trustworthy manufacturers of high-quality products will end up producing a dud every once in a while.
