Betta can live up to 5 years in an ideal 2.5-gallon tank with a filter and heater, but when placed in a bowl, it can live less than half of its life expectancy, and in some cases less than a year.

What tank size do betta fish and corydoras need?

Corydoras tank size

  • The minimum aquarium size is 10 gallons.
  • About 4 inches long, the cory catfish can live in tanks ranging from 5 to 10 gallons.
  • Large catfish require an aquarium of at least 30 gallons.
  • A 10-gallon aquarium can accommodate two to four core catfish.
  • A one inch catfish usually needs at least one gallon of water to live comfortably.

Betta fish tank size

  • Minimum aquarium size for a single fighting fish or betta fish is  3 gallons.
  • The additional aquarium size for each fully grown bettas is 1 gallons.
  • The ideal aquarium size for single male or female betta is 5 gallons.
  • Bettas do pretty well in bigger and spacious aquariums.

Are betta fish and corydoras aggressive in nature?

Cory catfish are not aggressive and do not pose a threat to smaller fish.Corydoras suck up food with their mouths and do not intentionally or accidentally bite other fish.

Social by nature, they are happiest when kept with at least three members of the same species.

Betta splendens are also known as siamese fighting fish because of their native species and aggressive nature.These fish are very aggressive and males often fight each other until they die.

Even female bettas can be aggressive, but usually more sociable than male bettas.

Do betta fish and corydoras need the same aquarium plants in their tanks?

Tank plants for bettas:

  • Live and overhanging plants are best for your bettas as they act as a natural oxygen purifier and can help them to conceal themselves to avoid aggressive tank mates or predators.
  • Java fern is one of the most well-liked plants in the aquarium hobby because of its long,thick leaves and low maintenance care.Anubias,marimo moss ball,cryptocoryne,water sprite,betta bulb,sword plant,vallisneria.
  • Indian almond leaves are recommended as they can keep their immune system strong.

  • Java fern
  • Amazon sword
  • Anubias nana
  • Water sprite
  • Moss balls
  • Hornwort
  • Java moss

Do betta fish and corydoras need the same light intensity in their tanks?

If you’re keeping live plants (which Corys love),you’ll need an LED light and betta fish need light to be truly physically and behaviorally healthy. Remember that you provide them with a regular day and night cycle so that they have a dark period when they can rest.

Do betta fish and corydoras need similar substrates in their tank?

Corydoras cannot live without sand. In the wild, corydoras live along the bottom of sandy rivers and have evolved to feed by sieving sand through the gills. Without sand, there is nothing to sift. 

To keep your corydoras happy and healthy, keep the bottom of the tank soft and natural sand. Corydoras have wispy barbels or whiskers to help them find food, so smooth sand or gravel is preferred.

The best choice will be fine sand for bettas.The two best substrates available for tanks are gravel and sand. Gravel is excellent because it makes it easier to fix plants and produce more beneficial bacteria.

Sand is good because it is easy to keep clean and less likely to hurt Betta. You can use marble or no substrate for them.

Is it easy to care for betta fish and corydoras together in the same aquariums?

Caring for a cory catfish is easy and straightforward. One of the best things is that cory catfish are easy to care for and they have calm, peaceful and non-aggressive temperament.

Some types of catfish are more shy and timid than others.Bettas need proper aquarium filtration, warm water, and a spacious aquarium to swim freely with enough hiding space to hide when overwhelmed. 

They should be fed nutritious food to maintain the color of their finnage.Waste in tanks will eventually produce ammonia spikes is very dangerous for them,so it’s very important not to overfeed them. 

Are they both perfect community fish?

Corydoras or Corydoras catfish, is one of the most popular community fish because of its cheerful nature, easy breeding, and useful as a cleaner.

Corydoras tank mates include most community tank fish as long as they are non-aggressive and inherently friendly.Bettas can be a good community fish but they cannot live with brightly coloured species, finnippers, aggressive fish and multiple male bettas together.

Female bettas are more sociable than male bettas.Male bettas get aggressive with one another and fight with each other to death.It is very important to have male and female bettas ratio maintained in tanks to avoid clashes.

Are they beginner friendly or for experienced aquarists?

Corydoras is a tough fish by its size and is a staple of freshwater community tanks.Care for Corydoras is easy, regardless of type. Care for corydoras is basically easy and is especially popular with beginner enthusiasts.

Bettas are good for both newcomers and experienced fishkeepers. They are very attractive, especially male bettas.These have specific water parameters and food habits to maintain their finnage colourtion.
