Cerith Snail (Cerithium sp.)

Clean-Up Crew • £2.50

Cerith Snail (Cerithium sp.) The Cerith Snail is a versatile and highly useful member of a marine clean-up crew. Recognised by its long, spiral shell and active grazing behaviour, this species contributes to algae control while also helping to maintain a healthy substrate. Unlike single-purpose grazers, Cerith Snails work in multiple areas of the aquarium. They move across rockwork and glass consuming microalgae, and they will also burrow into the sand bed in search of detritus and uneaten food. Their ability to work both above and below the substrate makes them particularly valuable in established reef systems. Behaviour & Role in the Aquarium Cerith Snails assist with: Film algae control Diatom grazing Detritus consumption Light sand bed turnover They are active both during the day and at night, often seen moving along rock surfaces before retreating into the substrate. Because they are smaller than Turbo Snails, they are less likely to disturb aquascaping. Care Considerations Cerith Snails thrive in established aquariums with stable water parameters and a sand bed. As with most marine invertebrates, they are sensitive to: Elevated nitrate levels Copper-based medications Sudden changes in salinity A slow drip acclimation process is recommended. If algae and detritus levels are very low, supplemental feeding may occasionally be required. Compatibility Cerith Snails are peaceful and fully reef safe.

Bumble Bee Snails

Clean-Up Crew • £2.50

Bumble Bee Snail (Engina sp.) The Bumble Bee Snail is a small but eye-catching marine invertebrate, recognised for its bold black and yellow banded shell. Beyond its distinctive appearance, it serves a functional role in the aquarium as a carnivorous scavenger. Unlike algae-grazing snails, Bumble Bee Snails actively seek out meaty debris and organic matter within rockwork and substrate areas. Behaviour & Role in the Aquarium Bumble Bee Snails are opportunistic feeders. In the home aquarium they may: Consume uneaten meaty foods Scavenge detritus Feed on small worms, including bristleworms Consume weakened, dying, or deceased snails While they are generally considered reef safe, they are not strictly herbivorous clean-up crew members. In systems with limited food availability, they may target small invertebrates. For this reason, they are best suited to established aquariums where natural food sources are present. They are not effective algae grazers. Care Considerations As with most marine invertebrates, Bumble Bee Snails are sensitive to: Rapid changes in salinity Copper-based medications Elevated nitrate levels Drip acclimation is recommended when introducing them to a new system. Because they are carnivorous scavengers, occasional supplemental feeding may be required in ultra-clean or low-nutrient tanks. Compatibility Bumble Bee Snails are peaceful toward fish and corals. However, caution is advised in systems containing very small snails or delicate microfauna. They are best introduced as part of a balanced clean-up crew rather than as primary algae controllers. Key Information Scientific Name: Engina sp. Common Name: Bumble Bee Snail Care Level: Easy Temperament: Peaceful Reef Safe: Yes (with caution in micro-invertebrate systems) Diet: Carnivorous scavenger Temperature: 22–26°C (72–78°F) pH: 8.1–8.4 Specific Gravity: 1.023–1.025 Maximum Size: Approximately 1–2 cm Origin: Indo-Pacific Family: Buccinidae

Mexican Turbo Snail

Clean-Up Crew • £4.00

Turbo Snail (Turbo fluctuosa) The Turbo Snail is widely regarded as one of the most powerful algae grazers available to marine aquarists. Known for its strong appetite, this species is particularly effective at tackling hair algae and other common nuisance growth on rockwork and glass. Its sturdy, rounded “turban-shaped” shell features a smooth outer surface and a subtly iridescent interior. Native to the eastern Pacific, including the Gulf of California, Turbo fluctuosa is well suited to stable reef aquariums with plenty of natural grazing surfaces. Behaviour & Role in the Aquarium Turbo Snails are active herbivores that spend much of their time moving across rock and glass in search of algae. Because of their size and strength, they can occasionally dislodge unsecured rockwork while grazing, so stable aquascaping is important. They thrive in systems that provide: Plenty of surface area for algae growth Secure rock structures Stable, mature water parameters If natural algae becomes limited, dried seaweed or algae-based supplements can be offered to prevent starvation. Care Considerations Like most marine invertebrates, Turbo Snails are sensitive to unstable water conditions. Particular attention should be paid to: Consistent salinity Stable alkalinity and pH Adequate calcium levels for shell development They do not tolerate copper-based medications and can be negatively affected by elevated nitrate levels. A slow drip acclimation process is recommended when introducing them to a new aquarium, as they can react poorly to sudden parameter changes. Compatibility Turbo Snails are peaceful and reef safe. However, they should not be housed with aggressive fish or invertebrates that may prey on snails. Key Information Scientific Name: Turbo fluctuosa Common Names: Turbo Snail, Turban Snail, Top Shell Snail Care Level: Easy Temperament: Peaceful Reef Safe: Yes Diet: Herbivore (primarily algae) Temperature: 22–26°C (72–78°F) Alkalinity (dKH): 8–12 pH: 8.1–8.4 Specific Gravity: 1.023–1.025 Maximum Size: Up to 5 cm (2″) Family: Turbinidae Origin: Eastern Pacific (including Mexico)

Turbo Snail (Astraea tecta)

Clean-Up Crew • £2.50

Turbo Snail (Turbo fluctuosa) The Turbo Snail is one of the most effective algae grazers available for marine aquariums. Well known for its appetite, this active snail will spend much of its time moving across rockwork and glass surfaces consuming film algae and other natural growth. Because of their strong grazing ability, Turbo Snails are often introduced to help control visible algae build-up in established systems. They can make a noticeable difference when used appropriately as part of a balanced clean-up crew. Turbo Snails have a solid, rounded shell and a sturdy build, making them suitable for most reef environments. They are completely reef safe and will not disturb corals or other invertebrates. Care & Aquarium Requirements Turbo Snails rely on adequate calcium levels to maintain healthy shell growth. Stable water parameters are important, particularly: Consistent salinity Stable pH Sufficient calcium levels Overstocking is a common issue. These snails require a consistent supply of natural algae, and too many in a small system may lead to starvation. As a general guide, allow approximately one Turbo Snail per 75–115 litres (20–30 gallons) of aquarium volume, depending on algae availability. If natural algae levels are insufficient, their diet can be supplemented with dried seaweed or algae-based foods. In tanks that already house strong algae grazers such as tangs or rabbitfish, stocking levels should be adjusted accordingly. Behaviour & Compatibility Turbo Snails are peaceful and suitable for community reef aquariums. However, they should not be housed with aggressive invertebrates or species known to prey on snails. They are capable of moving throughout all areas of the aquarium, including rockwork, glass, and substrate. Key Information Scientific Name: Turbo fluctuosa Common Names: Turbo Snail, Turban Snail, Top Shell Care Level: Easy Temperament: Peaceful Reef Safe: Yes Diet: Herbivore (algae grazer) Temperature: 22–27°C (72–80°F) Specific Gravity: 1.020–1.024 pH: 8.0–8.4 Maximum Size: Up to 5 cm (2 inches) Minimum Tank Size: 30 gallons Origin: Eastern Pacific (including Mexico) Breeding in Captivity: Rare

Banded Trochus Snails

Clean-Up Crew • £2.50

Banded Trochus Snail (Trochus sp.) The Banded Trochus Snail is a highly valued addition to reef aquariums thanks to its strong algae-grazing ability and hardy nature. Suitable for hobbyists of all experience levels, this active snail contributes significantly to maintaining clean rockwork and glass surfaces. Recognisable by its cone-shaped shell with natural banding and subtle striping, the Banded Trochus adds both function and visual interest to marine systems. Its sturdy shell structure also offers some protection from opportunistic tank mates. Unlike some similar grazing snails, the Banded Trochus has the ability to flip itself upright if overturned — an important trait that improves survivability in busy reef environments. Behaviour & Role in the Aquarium Banded Trochus Snails are constant grazers, feeding primarily on: Film algae Diatoms Microalgae Light cyanobacteria growth They are not aggressive hair algae consumers but will help control early-stage nuisance algae as part of a balanced clean-up crew. In mature systems with stable water parameters, Trochus snails may spawn. Spawning typically appears as a temporary cloudy release into the water column, often triggered by changes in lighting or water conditions. While larvae may develop in some systems, survival rates vary depending on filtration and tank maturity. Aquarium Requirements These snails thrive in established aquariums with stable water chemistry and sufficient natural grazing surfaces. If algae levels are low, supplemental feeding with dried seaweed or algae-based foods may be required. As with most marine invertebrates, they are sensitive to: Elevated nitrate levels Copper-based medications Rapid changes in salinity or temperature A slow drip acclimation is strongly recommended when introducing them to a new system. Stocking Guidance A general guideline is approximately one snail per 8–10 litres (2–3 gallons) of aquarium volume, depending on algae availability. Key Information Care Level: Easy Temperament: Peaceful Reef Safe: Yes Diet: Herbivore (algae grazer) Preferred Environment: Established reef aquarium Temperature: 22–26°C (72–78°F) Salinity: 1.023–1.025 pH: 8.1–8.4 Approximate Size: 1–2.5 cm (½″–1″) Origin: Indo-Pacific (varies by supplier)

Nassarius Snail

Clean-Up Crew • £2.50

Nassarius Snail (Assorted) The Nassarius Snail is a small but highly effective member of any marine clean-up crew. Although modest in size, this active scavenger plays an important role in maintaining substrate cleanliness by consuming uneaten food and organic debris before it can impact water quality. Unlike algae-grazing snails, Nassarius Snails specialise in detritus and leftover meaty foods. They spend much of their time buried beneath the sand bed, emerging quickly when they detect food in the water. Their natural burrowing behaviour helps to gently turn over and aerate the substrate, reducing compaction and improving overall sand bed health. These snails are best introduced to established aquariums with a mature sand bed. They are peaceful and fully reef-safe, posing no threat to corals or other invertebrates. As with most invertebrates, they are sensitive to elevated nitrate levels and copper-based medications. Breeding in captivity is rare, and most specimens are wild-collected. Key Information Care Level: Easy Temperament: Peaceful Reef Safe: Yes Diet: Scavenger (meaty foods, detritus) Preferred Environment: Established aquarium with sand substrate Temperature: 22–26°C (72–78°F) Salinity: 1.023–1.025 pH: 8.1–8.4 Max Size: Approximately 1–1.5 cm (½ inch) Origin: Tropical marine regions (varies by supplier)
