Black Orchid Betta is one of the most amazing and popular pets in the world. They are a variety in the Betta splendens species and are known for their beautiful colorful fins and body.  They are dark black in color with a butterfly pattern with blue colored stripes on their fins. 

Black Orchid Betta, also known as the Black Devil or Black ice, is one among the 73 species of Betta and is a type of Black Betta. They are known for their large magical flowing fins. Most of the fish in this species have a tinge of red, making their color more intense and more stunning to look at; however, their iridescent coloring is not something seen in just its fins. They grow up to a length of 3 inches. 

They are pretty common and are easy to breed and will be available at the nearest pet store, or one can buy Black Orchid Bettas online.
Black Orchid Bettas can live for up to three years on average. However, under proper care, they can live up to 5 years. They are very popular due to their majestic beauty and magical fins.

Origin of Rose Petal Betta

Breeder Henry Yin developed his own breed of dark bi-color crown tail betta and gave the name Black Orchid Betta to it due to its dark black color. They originated from South East-Asian countries, especially Thailand, Laos, and Cambodia. These fishes are members of the Gourami or the Osphronemidae family. They are generally seen in flood plains, water streams, and drainage ditches.

The Name

The name of this fish comes from the beautiful color they have on their body and fins. They have a beautiful dark black color with blue stripes, which vaguely resembles the color of the Black Orchid flower. However, the black color they have is not a marble-based black but a melano type. 

Food & Feeding of Black Orchid Betta

Black Orchids eat both vegetarian food and Insect larvae. However, their diet needs to be kept in check as it takes some time for the new Bettas to adjust to their new home. Therefore, they mainly consume mosquito larvae, bloodworms, and brine shrimp.

Black Orchid Betta should not be given live food brought from outside as it may contain pesticides and bacterias. They prefer dry foods like flakes and pellets. The diet should 40% based on meat with high proteins. Special frozen food will be available at the pet store; however, it needs to be soaked before feeding.

One must remember to not overfeed the Bettas as it could lead to a lot of health issues. 

Best Tank Conditions Black Orchid Betta

A minimum of 10 Gallons of water is needed in the tank to make sure there is enough space for the fish to swim freely. Black Orchids are not fast, swimmers, however, that does not mean they should be kept in small bowls or tanks as it needs a lot of space to swim around because of their large-sized fins. 

The tanks should be longer and not taller as the fish needs to be able to go to the surface to breathe however if the tanks are taller then it would mean they will have to swim more and as their tails weigh them down it would be harder for them to swim for longer. 

Black Orchids are also good jumpers and they jump when they are attacked by other aggressive fish in the tank. So in order to ensure the safety of the fish a lid needs to be there for the tank. The lid should be well fitted and needs to have a minimum distance of one inch between the water surface and the lid as they are good jumpers. 


The tank needs to be bright and should have proper lighting as Black Orchids prefer well-lit tanks and the lighting also helps to distinguish the colors of the fish properly.

Adding decorations and substrates makes the fish feel more at home and helps it ease into the new environment, and makes it feel comfortable with its surroundings. They also prefer to have plants in the aquarium to let it have space to hide if it feels unsafe. The decorations and substrates also provide a resting place for the fish as they need to rest often. 

Water Conditions 

Water needs to be clean always as an unclean tank could lead to various health issues for the fish.  The temperature of the tank should always be between 21°C and 29°C, and the temperature should never go below 20°C.

Bettas prefer the pH level of the water to be at its natural level, which ranges from 6 to 7.5 on the pH scale. The sudden fluctuation of the pH level of water can be deadly to the fish. So, one must ensure the pH of water always stays at the desired level. 


A tank needs a filtration system to ensure that it stays clean; however, it needs to be kept so that the outflow is regulated so there is minimal current in the water and the Betta can swim comfortably.

A filtration system needs to manage the nitrate level in the tank and ensure the uneaten food and organic wastes do not get turned into fungus and cause health problems to the fish. Therefore, it is also recommended to keep a fungus eliminator in the tank.
