How big does Snowflake Moray get?

Snowflake Moray reaches an adult standard length of 60–70 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 Snowflake Moray 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 Snowflake Moray?

At least 300 L, and no shorter than 120 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 Snowflake Moray like to keep?

Temperament: predator. Difficulty: moderate. It occupies the bottom and is carnivore. Reef safety is "Not reef safe".

Can Snowflake Moray be kept with its most common tank mate?

The checker returns "Not recommended together". Snowflake Moray and Ocellaris Clownfish is a recorded conflict in this atlas. Predation, territorial fighting or conspecific aggression is the usual outcome, and a bigger tank does not change it.

Keeping notes

1Preys on small shrimp and crabs; cleaner shrimp will not last.
2Needs a tightly sealed lid; morays squeeze through gaps of a centimetre or two.
3Teeth crush crustaceans rather than tear, but bites hurt; feed with long tongs.
4Large appetite and heavy waste; size the filtration generously.
5Knocks over anything unsecured, so glue every coral and rock in place.
