How big does Percula Clownfish get?

Percula Clownfish reaches an adult standard length of 7–9 cm (excluding the caudal fin). Size the tank for that, not for the juvenile you bring home — the difference is often several times over, and upgrading later costs more than buying once.

What water does Percula Clownfish need?

24–27 °C, pH 8.1–8.4, 7–12 dGH, 7–9 dKH, specific gravity 1.023–1.026. That is only 3 °C wide, so stability matters more than hitting a particular number.

What is the smallest tank for Percula Clownfish?

At least 60 L, and no shorter than 60 cm. That is the floor for long-term keeping, not for short-term survival: volume buys water stability and length buys swimming room, and neither substitutes for the other. It is not a schooling fish, so a single specimen or a pair is fine.

What is Percula Clownfish like to keep?

Temperament: semi-aggressive. Difficulty: beginner. It occupies the middle and is omnivore. Reef safety is "Reef safe".

Can Percula Clownfish be kept with its most common tank mate?

The checker returns "Can be kept together". Percula Clownfish and Royal Gramma is a well-established pairing. Individual fish still differ; the record says "usually fine", not "guaranteed".

Keeping notes

1Distinguish it from the ocellaris by the heavy black band margins; the two hybridize.
2Quarantine is essential; wild specimens carry higher ich and Brooklynella risk.
3Prone to slime-coat loss under parameter swings; change small volumes more often.
4Prefers carpet and bubble-tip anemones, but breeds and thrives without one.
5Completely reef safe; mixes well with peaceful gobies and grammas.
