WYSIWYG Blue Starlight Plakat Male Betta (Betta splendens)

This Blue Starlight Plakat Male Betta (Betta splendens) has a deep charcoal body that looks almost black until the light hits it, then a spray of turquoise and sky blue scales lights up across his head and shoulders like stars on a night sky. That contrast is where the "starlight" name comes from. His dorsal, tail, and anal fin carry a rich red that runs along the fin bases and into the tips, so he reads as a dark fish with a red trim and a blue sparkle up front. As a plakat he has the short, sturdy fins closest to the wild betta shape, which makes him quick, active, and far less prone to torn fins than long-finned types. He is hardy and a great choice for a first betta. Browse the rest of our live freshwater fish and freshwater supplies to set his tank up right.

Why WYSIWYG Matters on a Starlight Betta

On a speckled betta like this one, no two fish carry the same spread of iridescent scales. Some are covered nose to tail, some have a handful of sparks, and the balance of dark body, blue shine, and red fin is different on every fish. A stock photo tells you almost nothing about which one you would get. The photo on this listing shows this male in our tank as he looks right now. Metallic scaling can fill in and spread as a betta matures, and color usually deepens once he settles into a stable home and fades a little under stress or harsh lighting. Treat the photo as an honest starting point, not a frozen guarantee.

Care Guide

• Tank size: 5 gallons minimum, 10 gallons is better. Cups and bowls are survival, not living, and a heated, filtered, cycled tank changes how a betta behaves.
• Temperature: 78 to 82°F, and a heater is not optional. Cold water makes a betta lethargic and prone to illness, and a stable temperature matters more than hitting a perfect number.
• Gentle flow. Plakats handle current better than long-finned bettas, but he still prefers calm water. Baffle the filter outlet or use a sponge filter.
• Leave an air gap and use a lid. Bettas breathe air at the surface through their labyrinth organ, and plakats in particular are strong jumpers.
• Water parameters: pH 6.5 to 7.5, soft to moderately hard. Do weekly partial water changes with Seachem Betta Basics or Seachem Prime.
• Feeding: carnivore. Use a betta pellet like Xtreme Betta Floating Pellets as the staple, with frozen or freeze-dried bloodworms and brine shrimp two or three times a week. Small portions, a few pellets at a time.
• Decor: give him plants and resting spots near the surface, such as Anubias Nana and a ZooMed Betta Bed Leaf Hammock. Skip anything with sharp edges.
• One male per tank. Non-negotiable. Two male bettas in the same water will fight until one of them is dead.

Specifications

Compatibility

He can live in a community tank of 10 gallons or more if you pick the right neighbors: nothing that nips, nothing flashy enough to look like a rival, and nothing small enough to swallow. Good choices include a school of Ember Tetras or Kubotai Rasboras, a group of Pygmy Corys, Black Kuhli Loaches, or a Racetrack Nerite Snail. In a 5 gallon he is happiest alone, with a nerite snail at most.

Avoid fin nippers like tiger barbs and serpae tetras, long-finned or brightly colored fish like fancy guppies, and gouramis. Never a second betta. Temperament varies by individual, and plakats can be more assertive than long-finned males, so watch the tank for the first week and have a backup plan.

FAQ

Is the photo really this fish?
Yes. That is him in one of our tanks, photographed as he is now. That is what WYSIWYG means. There is one of him, so when he sells the page comes down instead of being restocked with a different betta.

Will his color change?
Probably a little. The blue speckling can spread or fill in as he matures, and his reds and blues usually deepen once he is settled in a warm, stable tank. Stress, cold water, and bright bare tanks wash color out, so a planted, heated home shows him at his best.

What is the difference between a plakat and a regular betta?
Plakats are the short-finned form, closest to how wild bettas look. They are faster, more active, and much less likely to tear or bite their fins than long-finned types. People new to bettas sometimes mistake a plakat male for a female, but the brighter color and bolder fins give him away.

Does he really need a heater and a filter?
Yes. Bettas are tropical fish that need 78 to 82°F, and a gentle filter keeps the water clean between changes. An unheated tank is the most common reason bettas turn sluggish and sick.

Can he live with another betta?
No. Male bettas are territorial and will fight, so he needs his own tank. Keep him away from female bettas too, outside of a supervised breeding setup.
