Frequently asked questions

The essentials: size, tank volume, water parameters and care

How big does Tussy's Betta get?

An adult reaches 3–4 cm in length. Plan the tank around the maximum size: the fish quickly outgrows a cramped setup.

What size aquarium does Tussy's Betta need?

The minimum recommended volume is 40 L. A smaller tank speeds up nitrate build-up and raises stress levels.

What water parameters does Tussy's Betta need?

Temperature 22–27 °C, pH 3–6, hardness 1–8 dGH. Stability matters more than exact values: sudden swings are harder on the fish than a small deviation from the ideal.

Around 4 years when kept properly. Lifespan depends directly on tank volume, water quality and a varied diet.

Is Tussy's Betta aggressive?

Temperament: peaceful (regular). Keep this in mind when choosing tank mates.

How many Tussy's Betta should be kept together?

Recommended setup: mixed (solitary / pair / group). Ignoring this is a common cause of stress and disease.
