Crowntail Betta

Geographic Origin and Biotope: Artificially selected variety in captivity, originated in Indonesia in the late 1990s. Does not exist in nature. Descended from the Betta splendens of the Southeast Asian swamps.

Taxonomy and Morphology: Crowntail Betta (Betta splendens CT mutation). Characterized by a drastic reduction of the membrane (webbing) between the fin rays. The protruding rays form distinct points, giving the fins (caudal, anal, dorsal) the appearance of a spiky crown.

Social Behavior: Strongly aggressive and territorial towards other males. Less agile than a Plakat due to the large fins, but extremely proud and snappy. Spends most of its time patrolling its territory.

Coloration and Sexual Dimorphism: Available in every imaginable color: from "Black Orchid" to red, blue, white or mustard gas. The male shows the typical crown and vast fins; the female has much shorter fins but also presents the typical jaggedness of the protruding rays.

Aquarium Setup: Dedicated aquarium (min. 20-30 liters / 5-8 gallons for a single specimen). Absolutely avoid sharp rocks or pointy woods that would fray the delicate rays of the crown. Real plants (Anubias) and total absence of current, which would exhaust it, are ideal.

Diet and Feeding: Insectivorous carnivore. Feed floating pellets for Betta alternated with live/frozen food to prevent constipation (primary cause of swim bladder problems). Be careful not to overfeed.

Water Quality: Crystal clear and warm water (26-28°C / 79-82°F) is essential. The very long ray extensions of the Crowntail are a magnet for bacteria and fungi: without meticulous water quality, the tips will rot (fin rot) in no time.

Compatibility and Tankmates: Isolated keeping recommended. Can tolerate snails (Nerites) or large shrimp (Amano), but often attacks them. Fast fish or Guppies (mistaken for rivals due to their voluminous tails) are absolutely forbidden.

Aquarium Reproduction: Bubble nester. More demanding than other varieties because the large fins hinder the male during the "embrace". Always remove the female immediately after spawning, otherwise the male will kill her.

Risks and Diseases: Fin Rot or Curling. If the water is too hard or polluted, the rays of the crown deform or "burn", losing their spectacular symmetry.
