Trochus Snail Starter Care Guide
A practical introduction to trochus snail care, including health risks, water quality, tank setup, food and behaviour.

About the Trochus Snail
Trochus snails are cone-shelled marine grazers that travel over rock and glass eating films of algae. They help with routine grazing, but they do not replace nutrient control or aquarium maintenance.
Some trochus snails can right themselves after a fall, but owners should still check rather than assume every individual can recover.
Health risks to know about
Important concerns include copper exposure, ammonia or nitrite poisoning, starvation in a spotless tank, salinity shock, damaged shells and being eaten by hermit crabs or predatory fish.
A snail that remains sealed inside, repeatedly falls, develops shell erosion, loses tissue or stops gripping surfaces needs prompt water testing.
Tank, water and equipment
Use a mature, fully cycled marine aquarium with established algae films, stable rock, safe glass access and no copper-based medication in the display tank.
Measure salinity with a calibrated refractometer. A specific gravity around 1.023 to 1.026 is a common invertebrate range, with calcium, alkalinity and magnesium kept appropriate for shell growth in a reef.
Food and feeding
Natural film algae is useful, but supplement with marine algae or a suitable complete herbivore food if grazing becomes scarce.
Watch body condition and activity rather than waiting for the tank to look completely clean.
Behaviour, tank mates and enrichment
Slow grazing across rock and glass is normal. Check any snail found upside down and return it gently if it cannot right itself.
Trochus snails are generally reef compatible, though they may dislodge very loose frags while climbing.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
