Giant Betta Fish Complete Care Guide (Breeding, Feeding And Tank Mates)

The giant betta fish (Betta anabantoides) is a type of freshwater ray-finned fish in the Macropodusinae subfamily, part of the gourami family. It is native to southern Kalimantan, the Borneo region of Indonesia. It is present in several river habitats and is a paternal mouth-broader. Giant bettas are well deserving of their name to their size. The appearance of the Betta anabantoides was the result of hard work and cautious, selective breeding. In 1999, Team giant created the first giant plakat through plakat betta fish.

The target is betta fish which reach at least 3 inches in length. But now there is evidence that they can grow to 5 to 7 inches long. They have also given rise to considerable controversy in the hobby. But Betta fish enthusiasts are some who are divided as to whether or not they believe that betta giantism is caused by a single gene.

GIANT BETTA

Simply the result of careful selective breeding for increased size. The reality may well be a mixture of the two at the end of the day. We know for a fact that significant bettas can be bred simply by selecting the largest fish to breed over successive generations.

Nevertheless, experiments conducted by Dr. Gene Lucas when giants first appeared they suggested that a partially dominant gene could generate the giant variation. As betta fish inheriting one copy of the ‘ giant gene ‘ grew larger than normal betta fish (so-called ‘ half-giant betta ‘) and betta fish carrying two copies of the gene became giants

What is a giant betta fish?

They are the same as regular betta fish (betta splendens), but the body size grows larger than traditional betta fish. They can grow up to 3 – 6 inches in general. But I have seen this fish that is 7 inches long. Brooders of this fish have used a selective breeding process when creating this marvelous fish.

Their fry is estimated to develop at a much faster rate than normal betta fish fry, needing much more food to reach its full potential. As a result, giant-normal size differences are clearly noticeable from just a few weeks old.

Young giants will be adults by 2-3 months old with proper food and conditions. So by 4 months old, they will be the size of your typical 8-month-old show betta fish.

As long as they are 7-8 months old, giants can reach at least 3 inches long. At about 6 months of age, the differences in body type are evident.

Finally, at a year old, they stop growing, but until they are around 18 months old, the fish can continue to put on width and weight.

Giant Betta Lifespan

Giants usually can have shorter lifespans because of poorer immune systems and are vulnerable to bacterial infections, so the lifespan of giants is considered to be short on average. But if you give good care the life expectancy goes up to 3-5 years.

Giant Betta Keeping Tips

With good care some giant betta strains will reach a length of three inches in a few months (including the caudal fin). The Giant Betta accepts quality flakes but prefers to consume live or frozen food. When grown-up, giants need less food. But, still able to eat more than twice as much protein as normal betta fish requires on a daily basis. Remember when you care, giants should be kept in larger containers than regular betta fish and receive more frequent water changes. Because of the increase in waste produced as a result of consuming a high amount of food

Are Giant Bettas Aggressive?

Yes, sometimes this fish can be adhesive. It depends on the individual fish. To look more impressive, male and female king bettas flare or puff out their gills to scare rivals or attract mates, as well as when they’re startled. They are not ideal for a typical community tank due to their aggressive nature, particularly towards fish species with long, flowing fins. All betta fish, also in solitary tanks, need a place to hide occasionally. They can set up a territory that they will guard aggressively, based on a plant or rock. Avoid keeping two male betta fish in a small tank. They will fight to death.

Giant Betta Care

Care for Betta fish is not a hard task. But you need to consider a few main things when caring for a giant betta tank. Hold Giant Betta in a tank with a lot of plants and a lot of hiding places. They prefer soft, slightly acidic, low-flowing water. Giants are a friendly species and the male can grow up to 5 inches in length. Fish are fairly easy to care for, but still require high water quality, as do all fish species, to ensure that they have an appropriate filtration system and that frequent changes in water are made.

Tank Size for Giant Betta

They need at least a 10-gallon aquarium or tank, but bigger is always better because they like to move around a lot. If you put them in a too-small aquarium or tank, they will never reach their full size. Always select a tank with enough space for them and not too deep. Some people keep them in a 5-gallon tank. But it is not recommended. You need a bigger tank to keep this beautiful fish.

Breeding

The giant characteristic is heritable and seems to be codominant for now. Simply put, if you raise female giant betta and male giant betta together, all offspring will be giants (although their final adult size will vary). 

If you mate a giant to a regular beta. Then the offspring will carry the giant gene and as a result, will grow to an intermediate size between the normal and the giant. Such fish are called ‘half-giants’. When you breed two carriers together it will give you 25 percent full-giants, 50 percent half-giants, and 25 percent normal bettas.

Male and female fish identification

When it comes to identifying bettas male and female, there are two main things you can look for: the size of their gill covers (the tissue on top of their gills) and the shape of their dorsal fin.

The size of the gill covers will vary depending on what gender your bettas are, but generally speaking, males have longer gill covers than females do. If you’re not sure which gender your fish is, simply turn them upside down—if they have a small, almost-invisible patch of white tissue on top of their gills, it means he’s a male!

The shape of his dorsal fin also varies between sexes: while the female has more rounded dorsal fins that curve slightly forward, male dorsal fins are much sharper and point straight out from just below his eyes.

Breeding bettas are similar to every betta species. You can find more details on how to breed bettas in here

Feeding

Betta Fish Giant consider as carnivorous fish. They live in South East Asia, where small insects and larvae make up the vast majority of their diet. The meat they normally eat is going to be high in fiber and protein. The insect they consume also contains nutrients from the food they have consumed in their stomachs.Keep in mind they do not eat plants.

If you were going to let your betta live off of plants in your tank, that is the worst feed you can give them. That being said, the odds are in the wild, they may sometimes consume plant life, but for them, there will be almost no nutrition.

How much to feed a giant betta?

In my experience, 8 to 10 pellets for one fish is enough if you provide them once a day. If you feed 2 times a day, 5 pallets for one feeding round would be enough. But this fish will require more food than regular betta fish because of their large body size. But keep an eye on their stomach while feeding; don’t let the stomach bulge too much because you can overfeed them. They have a big appetite especially providing them live food. So as I told you earlier, keep an eye on their stomach.

If you go out for a couple of days, instead of adding more to the tank, let the fish go without food. Ensure the feeding schedule is regular, and don’t worry if the fish doesn’t eat when stressed Bettas can go without food for up to 14 days before they die.

Giant Betta Constipation Solution

Adult fish are susceptible to constipation. Which, if not properly handled, can lead to death. Live brine shrimp and live or frozen daphnia should be made a daily feeding scheme because both these foods serve as a mild laxative.

Similarly, applying Indian almond leaves or leaf extract to the water of a giant betta fish is a good idea. The best treatment if the giant gets constipated is to starve the fish for a day or two. Also, it is common to add a little salt to the water. If the giant betta fish gets constipated feeding him the insides of a baked, green pea always helps make things move again. You should cut back on their feedings once they reach adult size. The best thing to do is monitor them continuously and care for them appropriately.

How do giant betta fish sleep?

They follow the normal sleeping pattern of fish, which you can read here. Also, they might sleep on rocks and plants in their tank.

History of them

According to the giant betta fish breeder Surat Bhutipanya, three Thai breeders who called themselves Team Giant produced the first giant bettas. Athapon Ratanapichad (Uncle Sara), his son Natee, and Wasan Sattayapun are part of this team. In 1999, Athapon and Natee found among the other bettas on their farm an unusually large green male plakat. Athalon had already found that his green bettas seemed to grow much larger than those of other colors, but it was more than three inches long.

The size of this fish was almost definitely the result of a genetic mutation (or genetic mutations) that may have increased the rate of development or caused anything that restricts growth in bettas. As it turns out, whatever the mechanism, this was a very lucky mutation for the betta hobby. In the hope of generating more giants and developing a whole new strain, the Ratanapichads bred this giant male to the largest female they had at the time. Only a small percentage of the fry grew to be big in the first generation.

Nevertheless, they were able to increase the percentage of giants in each brood by consistently selecting the largest fish for breeding in each subsequent generation. It took Team Giant as little as five generations to produce the first three-inch bettas, which made up about one-fifth of the spawning fry.

After produced giants

Once they had successfully produced giants, Team Giant began expanding their scope by outstripping those giants in a range of colors to standard-sized bettas of various other breeds. However they had to undergo the tedious process of selecting the largest fish from each brood each time they tried a new color in order to produce fish of the right size.

Due to Team Giant’s hard work and an ever-increasing number of breeders around the world, the giant beta is here to stay and is available in an ever-increasing range of shapes. Although the two most popular are asymmetric halfmoon betta and half-moon (and the eventual delta and super delta which come as part of the half-moon package).

  1. Where can I purchase a giant betta? Are they able to be put with other giants? Are they a community fish?

    • Chad, Petco giant bettas are not the same as real Giant Betta fish. They are of different strain and can only grow a maximum of 3-4″. You will need to find Giant Betta dealers from Thailand. Best place to find them is facebook by searching for them. There are a few on there that are pretty active.
