Freshwater Snails
Mystery Snail
Currently available in Jade -- a gold-shelled Pomacea bridgesii with a dark body that produces an overall olive-green appearance. Active grazers, shrimp safe, and unable to breed in a standard freshwater aquarium.
Mystery Snails (Pomacea bridgesii) are one of the most widely kept freshwater snails in the hobby -- large, active, visually striking, and genuinely useful as algae grazers and detritus processors. They are available in a range of colour variants including ivory, gold, blue, purple, and jade among others; we currently carry the Jade variant. Jade Mystery Snails have a gold shell and a dark body -- the combination of the two produces an overall olive-green appearance that integrates naturally into planted aquascapes without the visual loudness of brighter colour variants. Mystery Snails cannot complete their reproductive cycle in a standard freshwater aquarium, making population control a non-issue. They are peaceful, safe with all shrimp, and one of the most actively visible freshwater invertebrates available.
Current Variant
Jade -- Gold Shell, Dark Body
The olive-green appearance is a combination effect -- not a green shell -- the Jade Mystery Snail's shell is gold. The dark body and foot visible through and beneath the shell create the characteristic olive-green overall impression the variant is named for. The intensity of the olive tone varies by individual: darker-bodied individuals read as a deeper, more muted olive; lighter-bodied individuals trend toward a warmer yellowish-green. The effect is most visible from above and at an angle where both shell and body are simultaneously in view.
Naturalistic and understated compared to brighter Mystery Snail variants -- where Ivory, Gold, and Blue variants create clear colour contrast in a tank, the Jade reads as complementary to green aquatic plants and natural hardscape. It integrates quietly into a planted aquascape rather than standing out as an accent element -- a meaningful distinction in a shrimp tank where the shrimp are intended to be the visual focus.
Shell colour improves with adequate calcium and varied nutrition -- new shell growth laid down under good conditions is more evenly coloured and more lustrous than growth laid down in calcium-poor water. Consistent GH 6+ and regular feeding with algae wafers or blanched vegetables produces the best shell quality over the snail's lifespan.
Behaviour & Care
What to Expect
Cannot breed in a standard freshwater aquarium -- population fully stable -- Pomacea bridgesii lay egg clutches above the waterline on the tank glass or lid. In a standard covered aquarium the clutches desiccate and fail to develop. You will have exactly as many Mystery Snails as you introduce -- no unexpected population growth regardless of tank conditions or feeding.
Cover the tank -- Mystery Snails are escape-capable climbers -- this is the single most critical husbandry point. Mystery Snails are strong, persistent climbers and will exit the water and travel across dry surfaces if the tank has any gap. A tight-fitting lid with no openings larger than a few millimetres is essential. A snail found outside and returned promptly usually recovers; one left out for more than a few hours will not.
Active continuous grazer across all tank surfaces -- Mystery Snails graze constantly, covering glass, driftwood, hardscape, substrate, and decaying plant matter over the course of a day. They do not consume healthy living plant tissue. Their size and visible movement make them one of the most engaging freshwater invertebrates to observe -- far more visibly active than Nerite Snails of a comparable size.
GH 6+ required for shell integrity -- calcium is essential for healthy shell formation. In water below GH 6 the shell develops white patches, pitting, and thinning. Maintain GH 6+ at minimum; add a small piece of cuttlebone if your water is on the softer end. Standard Neocaridina water parameters are fully adequate.
Stock at 1 per 10–15L -- large bodied with proportionally higher waste output -- Mystery Snails produce more waste than smaller snail species. One snail per 10–15 litres is a reliable guideline in a shrimp tank to avoid water quality issues without additional filtration upgrades.
Fully safe with all shrimp at every life stage -- Mystery Snails are herbivores and detritivores and will not predate Neocaridina, Caridina, eggs, or shrimplets under any circumstances.
Keeper's NoteThe Jade variant is one of the few Mystery Snail colours that reads as more natural than decorative -- the olive-green sits comfortably alongside aquatic plants, brown driftwood, and dark substrate without competing visually with the shrimp. In a shrimp tank this is an advantage: the snail contributes meaningfully to grazing and detritus processing while the shrimp remain the visual focus. Pair with Fire Red Cherry or Sunkist shrimp -- the warm reds and oranges read more vividly against the muted olive of the Jade than they would against a brighter snail variant.
