Turbo Snail

Turbo fluctuosa

The big, hungry hair-algae eater — mows a bloom fast, but bulky enough to bump loose frags.

Difficulty: BeginnerCleanup crewReef-safe

The turbo snail (Turbo fluctuosa, the Mexican turbo) is the heavy machinery of the cleanup crew — a big, fast, ravenous grazer that can mow through a hair-algae bloom faster than any other snail. That power is also its downside: it's large and clumsy enough to bulldoze unglued frags, and in a spotless tank it can run out of food.

Good to know: Large and clumsy — can topple unglued frags; may run out of algae in a clean tank.

📊 What keepers actually ask: Bought as the "hair-algae fix"; the recurring problems are toppled frags and, once the algae's gone, a starving snail.

Care at a glance

Adult size	Large for a reef snail — up to ~2–3 in.
Minimum tank	Best in 30+ gallons (too big and hungry for most nanos); roughly 1 per 20–30 gallons.
Temperature	75–82°F (24–28°C).
pH	8.1–8.4.
Specific gravity	1.023–1.026 (reef-standard ≈35 ppt).
Other targets	Standard reef calcium and alkalinity keep the shell healthy; like all inverts it has zero tolerance for copper.
Diet	Voracious algae grazer — especially hair algae and film algae on rock and glass. Offer dried seaweed if algae runs low.
Temperament	Peaceful and reef-safe, but big and clumsy — it can knock over loose frags.
Reef-safe	Yes — it eats algae, not corals; the only risk is physical (bumping frags).
Natural range	Eastern Pacific (Gulf of California).

Beginner-friendly, done right. The go-to snail for a real hair-algae problem — few things clear a bloom faster. Two cautions: it's large, so it needs a tank with room and glued-down frags, and it eats so much that a clean, mature tank may not feed it (a starving turbo is a common, sad outcome — supplement with nori). Standard snail care otherwise: a cycled tank, drip-acclimation, no copper.

The fish store gets these wrong

Common myths, kindly corrected — no shame for having believed them.

"More turbos = a cleaner tank forever." They can strip a bloom in days and then starve — buy for an actual algae problem and feed them once it's under control.
"Turbos are nano-tank snails." They get big and hungry — they belong in larger tanks with room to graze.

Before you buy

A larger tank (30+ gal) with a real algae supply.
Glued-down frags — a turbo will bump loose ones.
A plan to feed nori once the algae's gone.
A cycled tank; drip-acclimate; never any copper.

Signs something's wrong

A struggling invert is usually telling you about water quality, acclimation, or (for shrimp and crabs) a fresh moult — here's what to watch for:

Toppled frags or rock — the turbo bumped them; glue things down.
Shrinking into the shell or inactive in a clean tank — it's starving; offer dried seaweed.
Empty shell — died from a swing, copper, or starvation.

Never

Never put a big turbo in a tank full of loose frags.
Never assume a clean tank feeds it — supplement.
Never add to an un-cycled tank, dose copper, or drop it straight in.

Common turbo snail questions

Are turbo snails good for hair algae?

They're the best snail for it — a big turbo can clear a hair-algae bloom faster than anything else in the cleanup crew. The catch is that once the algae's gone it needs feeding (dried seaweed), or it starves.

Are turbo snails reef-safe?

Yes — they eat algae, not corals. The only real risk is physical: they're large and clumsy and can knock over unglued frags, so secure your corals.

How big do turbo snails get?

Larger than most reef snails — up to about 2–3 inches — which is why they suit bigger tanks and can topple loose frags in small ones.

How many turbo snails do I need?

Fewer than you'd think — they eat a lot. Roughly one per 20–30 gallons, and mainly when you have an algae problem to solve.

Why did my turbo snail die?

Common causes are starvation in a too-clean tank, a salinity swing, copper, or being added to an un-cycled system. Feed nori when algae is scarce, acclimate slowly, and keep copper out.
