How big a fish tank does betta fish need?
1.Keep only one betta fish
○ Small betta fish: Like round-tail betta fish, the general length is about 1.5 to 2.1 inches. Choose a fish tank that is about 7.87 inches long to meet their basic living needs. If you want them to have more room to move around, an 11.81-inch square tank is a good choice. For example, if the width and height of a 7.87-inch long fish tank are both about 6 inches, then its capacity is about 1.19 gallons. Assuming the side length of an 11.81-inch square tank is 11.81 inches, the capacity is about 7.13 gallons.
○ Medium Bettas: For example, Thai Bettas are usually 2.4 to 3.1 inches long. At this time, it is best to use a fish tank that is 11.81 inches or longer. For example, a fish tank that is 11.81 inches long, 8 inches wide, and 8 inches high has a capacity of about 3.17 gallons.
○ Large Bettas: Some specially bred or strong Bettas may be longer than 3.1 inches. In this case, you have to choose a fish tank that is at least 15.75 inches long. If the fish tank is 15.75 inches long, 8 inches wide, and 8 inches high, the capacity is about 4.23 gallons.
2.Raise multiple Bettas
Bettas are naturally aggressive, and if a group of Bettas are raised together, they need a larger betta fish tank size, so that the number and intensity of their fights will be reduced. Generally speaking, you should use a fish tank that is 15.75 inches or longer. Also, put more driftwood, stones, water plants and other things in the fish tank so that the betta fish has a place to hide and can also divide its own small territory, so that there will be fewer fights. For example, a fish tank that is 15.75 inches long, 12 inches wide and 12 inches high has a capacity of about 9.51 gallons.
3.When breeding betta fish
When breeding betta fish, you need to prepare a separate, appropriately sized breeding tank for them. Generally, the breeding tank is 11.81 to 15.75 inches long, 8 to 12 inches wide, and 8 to 10 inches high. For example, a breeding tank that is 11.81 inches long, 8 inches wide and 8 inches high has a capacity of about 3.17 gallons; a breeding tank that is 15.75 inches long, 12 inches wide and 10 inches high has a capacity of about 7.92 gallons.
After introducing how to choose the right betta fish tank size, the next step is to choose the right fish tank accessories.
Recommended fish tank accessories
1.Filter
Betta fish have high requirements for water quality. A suitable filter can keep the water clean all the time. For small betta fish tanks, you can use a small wall-mounted filter, which does not take up space and can filter out dirt in the water. For larger fish tanks, use an external filter for better filtering effect.
2.Heater
Betta fish like to stay in warm water, with a water temperature of about 75 to 82°F (that is, 24 to 28℃). Choose a heater with appropriate power according to the size of the fish tank to keep the water temperature stable. If it is in a colder place, the heater is even more important.
3.Water plants
Planting some water plants in the fish tank is not only beautiful, but also gives the betta fish a place to hide, which reduces the pressure. Water plants such as moss water plants and water figs are very suitable for betta fish tanks. They do not require high light and water quality and are easy to keep.
4.Sinking wood and stones
Putting some sinking wood and stones in the fish tank can provide a natural environment for betta fish, and betta fish can also use them as a sign of territory. Choose those beautiful and hard sinking wood and stones, so that they will not hurt betta fish.
5.Special feed for betta fish
Buy good quality special feed for betta fish, which can meet the nutritional needs of betta fish. Occasionally, you can also feed some live bait, such as brine shrimp, water fleas, etc., which betta fish love to eat.
6.Thermometer
Check the water temperature in the fish tank at any time to ensure that the water temperature is appropriate. You can choose the kind of thermometer that can be attached to the fish tank or float in the water, which is convenient to look at.
In short, choose a good fish tank and accessories for betta fish, and they can live comfortably and healthily. When raising betta fish, remember to change the water frequently to keep the water clean and provide a good living environment for betta fish.
