Question 1

How much do betta fish cost in the UK?

Accepted Answer

Our bettas typically run from about £9 for veiltail males and females to £20-£23 for premium halfmoon plakat and koi strains. Prices on this page are live — what you see is what's in stock today.

Question 2

Can two betta fish live together?

Accepted Answer

Two males will fight, often fatally — never house them together. A male and female should only meet for supervised breeding. Female-only sororities of 4-6 can work for experienced keepers in a planted 60L+ tank, but even that needs a backup plan. The safe default is one betta per tank.

Question 3

What size tank does a betta need?

Accepted Answer

20 litres is the working minimum, heated to 24-30°C with a gentle filter. Bettas are tropical fish — an unheated bowl is the single most common cause of early death in the UK. Add a lid too: they jump.

Question 4

Is it safe to buy betta fish online?

Accepted Answer

Yes — arguably safer than a shop bag ride home. Each betta travels alone in an oxygen-charged triple bag inside a polystyrene-insulated box with a heat pack in winter, handed to a licensed live-animal courier. Dispatch is Tuesday-Wednesday, delivery Wednesday-Thursday, and every order has a photo-proof live arrival guarantee.

Question 5

Should I choose a male or female betta?

Accepted Answer

Males carry the long fins and intense colour most people picture; they must live one-to-a-tank. Females are shorter-finned but still vivid, slightly more active swimmers, and the only option if you ever want to attempt a sorority. If you want a centrepiece for a small planted tank, a male halfmoon plakat is the classic pick.

Question 6

What do betta fish eat?

Accepted Answer

A quality betta pellet as the staple, 2-3 pellets twice daily, plus frozen or live treats (bloodworm, brine shrimp, daphnia) once or twice a week. Skip one day a week — bettas are prone to bloat from overfeeding.

Question 7

Do you sell rare betta fish like alien, koi and giant bettas?

Accepted Answer

Yes — alongside classic halfmoon, plakat, veiltail and crowntail males we stock rarer lines including alien hybrids, koi and nemo plakats, samurai, hellboy, dumbo-ear and true giant bettas, plus wild-type Betta species. Stock rotates weekly, so check the live listings above — every fish shown is available right now.

Question 8

What's the difference between halfmoon and plakat bettas?

Accepted Answer

A halfmoon carries long finnage with a tail that spreads a full 180 degrees, bred for display. A plakat is the short-finned form — closer to the wild shape, typically more active and less prone to fin damage. Koi, copper and alien colourways appear in both. Care needs are identical: warm, filtered, cycled water.

Question 9

Can I buy betta fish online if there's no aquatics shop near me?

Accepted Answer

Yes — we deliver across the UK, so you don't need a local shop. Each betta travels individually in an oxygen-charged bag inside an insulated box, dispatched Tuesday or Wednesday with a licensed live-animal courier and covered by our live-arrival guarantee.

Question 10

Where do betta fish come from?

Accepted Answer

Betta splendens is native to Southeast Asia — Thailand, Cambodia, Vietnam and Laos — in the warm, slow, heavily planted waters of the Mekong basin. Wild bettas live in rice paddies, flooded fields and shallow ponds that stay in the mid-20s Celsius year-round, which is why a heated tank matters. Their labyrinth organ lets them breathe air at the surface, an adaptation to that low-oxygen habitat.

Question 11

How do I set up a betta fish tank?

Accepted Answer

Good betta fish tanks are heated to 24-28°C, gently filtered and fully cycled before the fish goes in — stable water quality, not size alone, is what keeps a betta healthy. Twenty litres is the working minimum. Leave a 2-3 cm air gap beneath a tight lid: the labyrinth organ means a betta must breathe at the surface, and they are determined jumpers.
