Blue Rim Plakat Betta

Blue Rim Plakat Betta - Sharp Blue-Edged Fins on a Sturdy Plakat Frame

The Blue Rim Plakat Betta stands out for the fine line of iridescent blue that traces the edge of its fins, framing the body colour with a clean, crisp finish. This is finished on a short-finned plakat form, giving the fish a compact, agile look rather than the trailing fins of show-type bettas.

That fine rimming detail is a selectively bred trait that takes a practiced eye to produce consistently, and it tends to become more defined as the fish reaches maturity. Beyond its looks, this strain carries the same robust constitution typical of plakat lines, tolerating a wide range of home aquarium conditions with ease.

At N8 Aquatics, our fish are carefully raised and conditioned to ensure healthy stock suited to home aquariums.

Species Snapshot

• Adult Size: 5–6 cm
• Tank Size: 20 L minimum, heated and filtered

• Temperature: 24–28°C
• pH: 6.5–7.5

Ideal Habitat and Care

A heavily planted tank with soft, low-flow filtration and plenty of surface cover suits this species best, as bettas are poor swimmers against strong currents.

• pH: 6.5–7.5
• Water Flow: Low to gentle
• Maintenance: Weekly partial water changes of 20–30%

Diet

This species is an easy feeder that will happily accept a varied diet.

• High-quality betta pellets as a daily staple
• Frozen or live bloodworm for extra protein
• Frozen or live brine shrimp as an occasional treat

Compatibility

This species is best suited to a species-only setup or a carefully chosen community of calm, non-fin-nipping tankmates, and should never be housed with other bettas or gourami.

Suitable tankmates include:

• A species-only betta tank
• Calm bottom-dwelling fish such as corydoras
• Peaceful, non-fin-nipping community species

Avoid aggressive or fin-nipping species.
