Male Black Crowntail Betta 5cm

Male Siamese Betta Black Crowntail

Betta fish are so incredibly popular for the array of bright and vibrant colours they are bred in however there is something simply stunning about a jet-black crown tail betta. This betta strain earns the name crown tail from the unique crown-like formation that its fins have. this genetic trait is present on all of the fins which gives a lion mane aesthetic. In males, this trait is especially pronounced and makes for an amazing display of fish in a small desktop aquarium and ticks all the boxes that beginner aquarists may want. 

Aside from their stunning fin structure, the solid jet-black colour on this fish is really eye-catching, especially against a vibrant background. When kept in a planted aquarium or a blue background tank the black crown tail will have an immense contrast which is simply not seen that commonly in the aquarium hobby. The jet-black crown tail is just like any betta in its care and behavioral requirements. Betta in general has developed a few false reputations, the first being that they can thrive in incredibly small environments like vases and jugs which is not true. Much like any aquarium fish, they need proper filtration and a spacious environment relative to their max size of 5 - 6 cm. The second common misconception is that they are aquarium terrors which will kill every fish on sight. Though male fighters are aggressive to other males and potentially aggressive in tight environments, in a standard 35L (10 gallons) aquarium they can be kept with other community fish. 

The black crown tail betta is also a hardy tropical fish that can be kept in temperatures between 24-28 and also make for a fun breeding project due to the challenge of continuing the male and female to breed and raise the fry. Betta is naturally found in the waterways of Southeast Asia.  

Tank Recommendations for your Male Siamese Betta Black Crowntail
Black crown tail betta maxes out at around the 5 - 6 cm mark and is a surprisingly active and flashy fish which is why they would be great in a nano aquarium with a minimum volume of 35 L. They will however be a great centerpiece fish in the larger peaceful aquarium with slow-moving fish. The substrate of the aquarium is not too much of a concern however crown tail fighters will love a well-planted aquarium. This allows them to contrast amazingly against the bright plants but also gives them a place of refuge to hide as well. 

Suitable Tank Buddies

Black Crowntail Fighters are relatively peaceful fish and actually often get bullied by other tank mates who nip at their trailing fins. Their slow nature also means they can get easily outcompeted during feeding time which is why care should be taken when selecting tank mates.

Usually Compatible

Small tetras such as neon, ember, rummy nose, and similar species. 

Sometime Compatible

dwarf cichlids such as Bolivian rams, or Apistogramma which may show aggression, or fast-moving species such as giant danios, torpedo barbs, or Congo tetras which might outcompete for food.

Rarely Compatible 

Shrimp, other male betta, tiger barbs, and larger species such as torpedo barbs will certainly outcompete the slower betta.
