Is the Scarlet Badis suitable for beginners?

The Scarlet Badis is generally considered a fish for more experienced keepers. Its reliance on live or frozen foods and need for stable water quality make it better suited to hobbyists with some aquarium experience.

Can it be kept with other fish?

Since it's shy and a slow feeder, avoid pairing it with fast, boisterous fish that will out-compete it for food. Peaceful small tankmates, or a species-only setup, work better.

What should I feed it?

Frozen bloodworms, brine shrimp, and similar live or frozen foods form the core of its diet. It rarely takes dry flakes or pellets, so plan feeding accordingly.

How big does it get, and how long does it live?

Adults reach only about 1.5–2 cm, and typical lifespan is around 3–5 years.

How can I tell males and females apart?

Males typically show more vivid red coloration overall, while females tend to appear more subdued. Coloring varies between individuals, so it helps to compare several fish side by side.

Scarlet Badis

The Scarlet Badis is a tiny jewel of a fish, reaching just 1.5–2 cm as an adult, with males flashing a vivid red that stands out beautifully against a planted tank. Despite its size, it's a true micro-predator, stalking small live prey from behind cover rather than grazing in the open. Because it rarely accepts dry food and needs a diet of live or frozen foods, along with stable water quality, it's generally considered a fish for more experienced keepers. For aquarists ready for the extra attention, it rewards with striking color and quietly fascinating behavior.

About Scarlet Badis

Scarlet Badis: a jewel-toned micro predator fish reaching just 1.5–2 cm, prized for its vivid red males. An advanced-keeper species relying on live and frozen foods.

7 things to know before welcoming a Scarlet Badis

1Needs Live or Frozen Food
Scarlet Badis rarely accepts dry flakes or pellets, so its diet centers on frozen bloodworms, brine shrimp, and other live or frozen foods. This makes feeding more hands-on than with typical community fish.
2A Tiny Predator by Nature
This species behaves like a miniature ambush predator, lurking near cover and darting out at small prey rather than schooling in open water. Feeding routines should account for this hunting style.
3Choose Tankmates Carefully
Because it's shy and a slow, deliberate feeder, boisterous or fast-eating fish will easily outcompete it for food. Peaceful, similarly small tankmates — or keeping it alone — tend to work best.
4Provide Plenty of Hiding Spots
Dense plants and driftwood that break up sightlines help this fish feel secure and reduce stress, which in turn supports better coloration. In an open, bare layout it tends to stay hidden out of sight.
5Stable Water Quality Matters
Sudden water quality swings, or a newly cycled tank, can put unnecessary stress on this species. It does best in a mature, well-established aquarium with minimal fluctuation.
6Males Are Territorial
Males will spar over territory, especially in tight quarters. If keeping more than one male, add extra hiding spots and space so they can establish separate territories.
7Watch for Small Gaps
Its tiny body can slip into filter intakes or small gaps around the tank that would stop a larger fish. Fitting a sponge pre-filter and checking for gaps ahead of time helps prevent accidents.
