Yellow Betta Fish Species Profile and Care

Yellow betta fish, also called goldens or goldie, are the most common color of all Bettas available. Their scientific name is Betta splendens. The yellow body with dark tail and fins may be solid in color or have a slightly darker shade on their dorsal fin.

Yellow Betta Fish Species Profile and Care

Bettas are anabantids, which means they have special organs called labyrinths that allow them to breathe air at the surface of the water. This adaptation allows bettas to survive in poorly oxygenated water conditions like rice paddies and shallow ponds in Thailand, where they live in the wild.

Yellow Betta Fish Origin

The name “plakat” means fighting fish in Thai language because it is derived from a local species of fighting fish found in Southeast Asia. Plakat colors often emulate the colors of local wild species, such as the Betta imbellis, which is a red and black betta with white edging.

Yellow bettas are actually created by crossing a female orange or red (wild type) betta to a male plakat (fighting fish). This makes yellow plakats an inter-species hybrid — just like mules.

Yellow Betta Fish Size

The average size for adult males is 1 ½ inches/ 4 cm and 2 inches / 5 cm for females, but it may vary. The tail fin itself should grow no longer than 50% of its body length in order to avoid injuries during fighting sessions with other male Bettas. If it’s longer, it will cause stress and lead to fin rot.

Yellow Betta Fish PH

The ideal water parameters for healthy bettas are slightly acidic (6.5-7) and temperatures of 76 degrees Fahrenheit / 24 degrees Celsius. Small changes in temperature or pH can cause stress or illness in Bettas, so make sure these factors remain stable. Because they come from shallow rice paddies, yellow bettas are used to living at the top of the tank where oxygen levels are low, so it’s important not to keep them in deep tanks that have high water turnover rates.

Yellow Betta Fish Colors and Markings

Varying shades of golden red for plakats is usually the most common betta color combination. Their dorsal fin is typically black with the rest of the fish being yellow or golden red, but veiltail plakats that are solid yellow, for example, are also available.

Because the young males usually show their best colors when they are ready to breed (up to two years old), it’s important to choose healthy specimens who consistently display vibrant beautiful colors. The better colored the male is, the more value he will have as a breeder and potential future father of your fry.

Yellow bettas like slower tank water flow and warmer temperatures like other Bettas do (76 degrees Fahrenheit / 24 degrees Celsius). Because their fins can easily tangle, it’s best to keep them in a tank alone or with peaceful fish who don’t nip.

Yellow Betta Fish Tankmates

Because they are very active and enjoy exploring every inch of their surroundings, yellow bettas should be kept in groups of 5 or more because they can become stressed when they are the only fish in the tank. They are good community fish but may show aggression toward other male Bettas if they feel that another male is infringing on their territory. It’s important not to keep multiple males together because fights can break out which can end up harming both Bettas. If you’re keeping your ‘enemy’ next door, always have a divider so there is no way for him to get to the other fish.

Yellow Betta Fish Care

Yellow Betta Fish Species Profile and Care

Special care should be taken when choosing live plants to decorate their tank, or they can become an easy snack. You will have more success if you choose slow growing plants that are silk or plastic rather than real ones, because some Bettas simply don’t recognize them as living creatures and can bite through plant stalks causing them to die. This is especially important for new pet parents who may not know the signs of betta illness yet.

Yellow Betta Fish Lifespan

Bettas typically live 1-2 years on average but with good care, it’s possible for some yellow bettas to live up to 5 years in captivity! Healthy Bettas fed a good diet and kept properly will show signs of excitement when their owner comes to feed them or clean their tank, including flare-ups and flaring their gills.

Yellow Betta Fish Diet and Feeding

Bettas are carnivores so they need a high protein diet consisting of some live foods along with pellets or freeze dried options. Overall, a varied diet will give your fish the best nutritional value for his or her size and life stage. As juveniles, Bettas should be fed 3-5 times daily but as adults only 1-2 times per day is required. If you don’t have time to get fresh food every day, there are specialty betta pellets that contain all necessary nutrients in one meal.

Yellow Betta Fish Differences

The yellow betta is a naturally occurring genetic mutation of the Siamese fighting fish. As their name suggests, they are not really a separate species from other bettas but rather simply have different coloration from standard Bettas. They tend to be hardier than wild Bettas because they do not live in water that is as poor quality or unpalatable as rice paddies which wild Bettas come from so keep this in mind if you’re thinking about purchasing one of these beautiful fish! Blue and green iridescence with some orange plakats also exist, but the most common variety is the golden red with black fins combination. When it comes to showing off his best colors, however, the female betta may be more vibrant than any of his male compatriots.

Yellow Betta Fish Breeding

Breeding yellow Bettas is not difficult, but like all other bettas they have their own demands when it comes to breeding conditions. When you are ready to breed your fish, make sure that you have a large tank so there is room for up to 20 fry which can grow almost an inch per month during the first few months! If you do not want this many fish in your home, then just remove the parents after spawning and place them back into the main aquarium or another temporary container until new homes are found for them. It’s important to keep up with water changes because of all the waste these little babies can put into the water!


The yellow betta is a very unique fish who has its own demands when it comes to care but thrives with the utmost pampering. They are special because of their coloration which makes them highly sought after by both collectors and pet parents alike, so if you’re thinking about adding one of these beautiful fish to your aquarium, make sure that they have plenty of room or they may become aggressive towards others close by including other Bettas! A tank full of large rocks and plastic plants will help keep everyone happy and healthy.
