The Community Tank Myth

One of the most common myths plaguing Betta fish is that they are brutal killers that will tear apart any fish or other creature placed in its territory, making it impossible to establish a community tank with this solitary species. This myth is often perpetuated by pet stores and pet supply stores to sell low-volume, typically less than 1 gallon, overpriced Betta fish tanks.While it is true that two male Betta fish should never be placed in the same undivided tank, no matter how many gallons it contains, it is untrue that all fish species are incompatible with Betta splendens. It should also be noted that female Betta fish are able to be grouped together in what is called a sorority, so long as there are at least 5 to 7 females in the tank and that there are no overly-aggressive ones that will disturb the sorority balance.

When considering the establishment of a community tank with a Betta fish, it is important to take tank volume into account. While many pet stores still advertise the old rule of one inch of fish per gallon, this is a misleading way to figure out how large of a tank is needed to build a community. If this rule was taken literally, it would mean that in order to have 10 one-inch fish in a single tank then a 100 gallon fish tank would be needed. However, this is not the case since there are many deciding factors that determine the minimum volume needed for various communities. Such factors include filtration, bioload, and the presence of live plants.

Because of these varying factors, there is no minimum for community tanks. Since a community tank can technically include merely having a single Betta fish and a single snail, it is also a loose term. Generally, though, most community tanks that will contain more than one fish living together will need at least 10 gallons. A small sorority of female Betta splendens, for example, cannot live in less than a cycled 10 gallon fish tank.

Depending on the desired tank mates, the required care for each species, and other wants for a community tank, a different minimum volume is needed. Because of this, it is important to do research behind each species that will be considered and added into a community tank. Schooling species are often popular with Betta splendens but those usually require around groups of 5 to 6 at the minimum each and different species produce different bioloads. Keeping this in mind is just as important as considering compatibility with Betta fish in order to run a healthy, happy, community fish tank.

Considering Stock for Your Community Tank

Because, like people, all fish have different personalities, they may not always get along with each other even if they are compatible tank mates. This is especially true when it comes to Betta fish, with individual Betta fish possibly being more territorial than other Betta fish of the same species and thus they may attempt to kill any addition to its territory while others may have the opposite reaction. This should be kept in mind when attempting to stock a functioning community. A school of tetras, for example, may be purchased and incompatible due to personality reasons and what to do with the incompatible fish needs to be taken into consideration.

The following are generally accepted tank mates for Betta splendens:

Please note that some of the schooling fish can be placed by themselves but prefer to be in a school, while others must remain in a school. Various cory catfish can school together.

Before stocking, all species must have research done on them in order to determine what good mixes are. Finding out their bioloads (high or low), water conditions, live plant needs, and other details that may pertain to the type of tank being considered is a requirement for a successful community. Betta fish should be added after establishing a community inside the tank because otherwise the Betta may become territorial and not welcome any newcomers. Be sure to watch the other fish too--tetras have been known for picking on Betta fish by biting their tails. This can sometimes lead to death or infection.

Before adding fish to a community, it is also necessary to quarantine the species in order to ensure a healthy addition. Diseases can easily be spread in a tank through careless adding of new tank mates and can potentially wipe out an entire community.

Recommended Water Changes for Betta Splendens

The following information is taken from a much larger article on this blog and separated like this for ease of finding it. The full article and sources, which cover water quality and the Nitrogen cycle, can be found here.

Water Change Schedules for Best Tank Health

A clean source of water is an assurance of better betta health. However, water changes are dependant on tank size. This next section is a basic guide to the most popular tank sizes used for betta fish. Bigger is always better and means less changes, especially if cycled.

1 gallon: Do a 100% water change every other day. This sized tank cannot establish a water cycle as it is too small.

2 gallons: 50% water changes 2-3 times a week and one 100% water change weekly. Another tank size too small for easy cycling, it is important to maintain regular water changes. Gravel vacuums will make cleaning easier and help maintain better water.

5 gallons: This is the first tank size that can be cycled by beginners and thus is has two different water change schedules. For cycled tanks, perform 50% water changes weekly. For non-cycled tanks perform 50% water changes twice a week and one 100% water change weekly. Non-cycled tanks are much harder to clean and it is recommended that a cycle is established for the this purpose.

10 gallons: For cycled tanks, perform 50% water changes weekly if there is only one betta inhabiting it. If it is a community tank, add another 50% water change to its schedule. For non-cycled tanks 50% water chanes should be performed twice a week and a 100% water change bi-weekly.

20 gallons: Tanks this size should only be cycled. 50% water changed should occur each week.

There are many other tank sizes but these are some of the most common. For in-between sizes, adjust the schedule to your best judgement. Although these are not absolute, strict, must-have schedules, they are recommended for the best health of betta fish.

The Misleading Label Scam

Betta fish are marketing gold mine. The care myths surrounding this popular pet species have lead to poorly designed and sometimes outright dangerous products that companies claim are specifically created for their well-being. Betta fish are misunderstood. Because they are misunderstood, product companies and product distributors take advantage of that fact and slap the ever-so misleading “for betta fish” label on everything—regardless of whether or not the product is safe or delivers what it promises.

The easiest place to spot these fraudulent products is in big-name pet chains, such as Petco, PetSmart, Petland, PetSupplies Plus, or Pets at Home. Outside of pet stores there are product carriers such as Walmart, K-mart, and even grocery stores carrying these dangerous or useless products. These products will range from too-small fish tanks to specialized water. The species-specific care myths are not researched beforehand by consumers and this make the sales of these “betta products” easier to push onto the buyer.

To put it bluntly: the majority of products that are specifically labeled as for betta fish are almost always scams.

The Fish Tank Scam

The majority of fish tanks specifically marked for betta fish are extremely overpriced and even deadly to fish. The myth that perpetuates sales of these tanks is the myth that betta fish naturally live puddles in the wild, thus they do not need much room to thrive. This is false. As explained in depth in the fish tank debate article on this blog, low-volume fish tanks are not suitable homes for betta fish because they do not cover the basic needs of the animal let alone provide an environment in which it can thrive. Nonetheless, pet stores and pet product distributors are fans of so-called betta tanks.

Petco is largely guilty of this fish tank myth continuing to circulate. Not only does the retailer provide outright false information on their care sheets, such as their claim that betta fish only need0.4 gallons to live in, but their specifically betta labeled products endorse their false claims. Some of their products even directly contradict what they claim on their betta care sheet, such as their own “Petco Dual Betta Bowl” that holds 0.3 gallons and comes with a divider to hold two male betta fish.

This tank is a company-created deadly product that is overpriced, regularly going for $8.99, and is purchased simply because it has the betta fish label. This fish tank, by Petco’s own claims in addition to what the fish actually needs to live, is hazardous for one fish let alone two. Aside from unsupported features this tank boasts on the website, the description of this tank urges consumers to purchase other betta-specifically-labeled products from the Petco brand.

Petco not only creates and sells their own brand of deadly products they claim are tailored to betta fish care but they also sell other companies’ products that are just as dangerous for fish health. The “Marina Betta Kit,” for example, is a product that is sold in Petco and other major chain retailers. It is 0.5 gallons, half of what the minimum is required for a betta fish, and comes with conditioner, food, and a plastic plant. The food, also labeled as for betta fish specifically, and the conditioner, which has the same label pattern, are inferior products that do not fully benefit the betta fish species. Additionally, plastic plants, which often come with these betta kits, are notorious for shredding the delicate fins of long-finned males. But the product grips consumer attention with opinionated claims such as “a dramatic aquatic display” and “a maximum view design that lets you enjoy your betta fish from every angle.” All this means is that the tank is clear, which is nothing spectacular since fish tanks are almost always clear.

Such empty pretend benefits listed as a feature of the betta specific tank are common. When a product cannot boast of anything substantial, companies use filler phrases to make it seems more worth the consumer’s money. The particular danger of the Marina kit and others like it, is that they claim to be complete kits for betta fish care while neglecting to include or even mention necessities such as a heater. These tanks trick potential buyers with the betta fish label and ultimately mislead about betta fish care and/or requirements, harming this welfare of this species.

Walmart is another major contributor toward harmful and deadly betta fish labeled tanks. In order to compete with major pet retailors, the company has created its own brand called Aqua Culture. This brand is cheaply produced with poor quality products and is often the majority of Walmart betta fish product stock. Aqua Culture tanks are often too low in volume for betta fish to survive in yet are specifically advertised as betta fish products. Their “Betta Cube with LED Light” tank is at a mere 0.3 gallons without a lid or necessary space to fit a heater. This product lists on its features a “unique design,” that it is “perfect for desktop,” and how it “compliments any room.” Once again, consumers are faced with opinions rather than facts about the product.

In addition to empty claims, the tank is on sale for $14.97 online. A non-betta-specifically-labeled 2.5 gallon fish tank costs a little less than that in PetSmart and around that price online. The higher price is simply because it has the betta label on it. Yet it does nothing to benefit the fish and certainly does not help the consumer’s wallet. Many of the betta-specific fish products are like this in Walmart and similar retailers, often dangerous and expensive.

The General Product Scam

In addition to deadly tanks and misleading or completely false information, general products with the betta fish label are also not necessarily good for this fish species. Petco and other pet stores have begun selling betta-specific water. The fact that there are not other bottles for other specific fish species should strike the consumer odd at the very least. The store claims the water is a “one step water change,” has no “chemical additives” or “chlorine or chloramine,” and is “super oxygenated.”

Betta water is the ultimate product scam. These bottles are often sold in volumes no larger than 1 liter, going for between $4 to $8 dollars each depending on the retailer. The bare minimum amount of water needed for a betta fish is 1 gallon or 3.78 liters. A 1-gallon tank needs a 50% water change and a 100% water change each week. That means a consumer would have to spend around $16 to $20 a week on this betta water. But is it worth it?

The claims on the bottle are true. It does not have chemical additives, chlorine, or chloramine that are found in tap water, making the water safe for human consumption. However, what the label does not tell the consumer is that this can also be accomplished by buying a small bottle of water conditioner, such as the highly rated Seachem Prime or API Stresscoat, for around the same price of a single bottle of this betta water. Water conditioner removes harmful ailments from tap water and only needs a few drops per gallon to work. A small bottle of water conditioner can easily last over a year or more depending on tank size and water change schedules.

As for the claim of being “super oxygenated,” that means nothing. An air pump or live plant can help add extra oxygen to the water, if needed. Once this bottle water is opened, any extra oxygen it may or may not contain will be exposed to the air and dwindled anyway.

While not all products with a betta label—such as food, floating logs, and so forth—may be scams, it is important to carefully think about what the product is claiming and to check if it is actually beneficial to the animal. More often than not, companies will sell any product that will make them money. The betta fish label makes it easier for them to do so. It is not the first time or the last that a product producer will manipulate or take advantage of the public in order to make an extra dollar.
