Plakat Betta

Betta splendens 'Plakat'

AnimaliaChordataActinopterygiiOsphronemidae

Variety of Halfmoon Betta · plakat

📍 Thailand & Cambodia

Ask Finn

The Plakat (from the Thai word for fighting fish) retains the shorter, rounder fin shape of wild Betta splendens, close to the original form before centuries of selective breeding. It is a more active, stronger swimmer than long-finned varieties and is less prone to fin damage and disease. Plakats are popular in Thailand, where fighting fish culture originated, and make excellent display fish in planted tanks.

Care Guide

Diet

Plakat Bettas are strict carnivores and should be fed high-quality betta pellets as their staple diet, supplemented 2-3 times weekly with frozen foods like bloodworms, brine shrimp, or daphnia. Feed small portions once daily, only what they can consume in 2-3 minutes, as they are prone to overfeeding and constipation. Avoid plant-based foods and flake foods designed for community fish.

Behavior

Plakats are highly aggressive toward other males and will fight to the death if housed together, earning their reputation as fighting fish. They are more active and energetic swimmers than long-finned Bettas due to their shorter, rounder fins, and they readily explore planted tanks and interact with their environment. Males are territorial and may display aggression toward females outside of breeding periods, and they can be nippy toward slow-moving or long-finned tank mates.

Breeding

Breeding Plakat Bettas in captivity is moderately difficult and requires careful conditioning of both sexes and precise water parameters. Males build bubble nests and will guard fry aggressively; females must be removed immediately after spawning to prevent injury or death. Fry are small and require infusoria or liquid fry food for the first week before graduating to micro pellets.

Common Diseases

Fin Rot

Symptoms

Fraying, discoloration, or deterioration of fin edges; often starts at fin tips and progresses toward the body

Treatment

Perform 25-50% water changes every 2-3 days, maintain pristine water quality, and treat with aquarium salt (1 tsp per gallon) or antibacterial medication if severe

Ich (Ichthyophthirius multifiliis)

Symptoms

White spots resembling salt grains on body and fins, rapid breathing, lethargy, and rubbing against objects

Treatment

Raise water temperature gradually to 28-30°C, treat with aquarium salt or commercial ich medication, and perform daily water changes until spots disappear (7-10 days)

Velvet Disease (Oodinium)

Symptoms

Fine, dusty gold or rust-colored coating on body, rapid gill movement, loss of appetite, and lethargy

Treatment

Increase temperature to 28-30°C, reduce light exposure, treat with copper-based medication or salt, and ensure excellent water quality with frequent water changes

Constipation

Symptoms

Bloated appearance, lethargy, loss of appetite, and inability to produce waste

Treatment

Fast the fish for 2-3 days, then feed small amounts of blanched peas or daphnia; ensure varied diet and avoid overfeeding
