Now, one question that we see asked every single month is why are betta fish kept in small tanks and this is such an important topic to cover so we wanted to publish our own article going over the subject.
Many of the people that we see reaching out and asking for advice on getting their first betta fish are rightly concerned about the tiny tanks and sometimes even cups that you can find better fish being kept in with many people wondering if it is cruel to keep the fish in such a small space. Our regular readers will already know that we love seeing people be responsible when it comes to the care of their fish and it is great that you have reached out about this as keeping betta fish in such a small space is one of the most common mistakes that we see from the community time and time again.
Why Are Betta Fish Kept In Small Tanks?
The main reason that you see betta fish kept in small tanks in pet stores is either due to uninformed pet store staff or a pet store owner trying to increase the number of fish they can store in a limited space. Betta fish should never be kept in a small tank with a male betta fish usually needing an aquarium of at least 5 gallons with no other tank mates as an absolute minimum.
Thankfully, there are some excellent, cheap 5 gallon aquariums on the market that first time betta fish owners are able to pick up to keep their new betta fish in. Although a single male should be kept in those 5 gallon tanks, there are ways that you are able to set up a 5 gallon betta sorority tank for multiple female bettas but it is generally to small and a 10 gallon sorority tank is recommended.
Now, a 5 gallon aquarium really is the absolute minimum tank size that we would recommend that our readers use to keep their pet betta fish in with most experienced fish keepers choosing to use a cheap 10 gallon tank. This offers more space for the betta fish to enjoy and offers a much higher standard of life for the fish while also offering ways to add tank mates to your betta fish tank such as an algae eater.
