How big does Flame Angelfish get?

Flame Angelfish reaches an adult standard length of 8–10 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 Flame Angelfish 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 Flame Angelfish?

At least 150 L, and no shorter than 90 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 Flame Angelfish like to keep?

Temperament: semi-aggressive. Difficulty: moderate. It occupies the middle and is omnivore. Reef safety is "Use caution".

Keeping notes

1Dwarf angels pick at LPS and soft corals; risky in a coral tank.
2Individual variation is huge; some never touch coral, others start within a week.
3Getting it feeding is critical; quarantine and tempt with brine and mysis.
4Keep a single dwarf angel per tank to avoid chronic chasing.
5Microalgae and sponges on live rock are important natural foods.
