About
Malaysian trumpet snails spend the day underground. The shell is a long, pointed cone, and the animal uses it to burrow through the substrate, coming up mostly after dark — which is why keepers often have hundreds before they realise they have any.
Underground is where their value lies. They tunnel constantly through sand and fine gravel, turning it over, stopping it compacting and breaking down anything trapped in it. In a deep substrate that work genuinely improves the tank.
They're also the most reliable overfeeding alarm in the hobby. Their numbers track available food precisely, so a substrate suddenly boiling with trumpet snails at lights-out is telling you exactly one thing about your feeding.
Tank setup
Give your trumpet snails a sand or fine gravel bed with some depth to it. That's their habitat, and in a bare-bottomed tank they lose most of what makes them useful.
Keep the water hard. Their shells erode badly in soft acidic water, and a heavily eroded trumpet snail loses the pointed tip that lets it burrow.
They tolerate a very wide range otherwise — temperature, pH, flow, light. This is among the most adaptable animals you can put in a tank.
Accept that you cannot easily remove them once established. They're in the substrate, they breed without a partner, and the young are minute.
Feeding
Trumpet snails eat detritus, biofilm, algae and anything organic that has settled into the substrate. They find all of it themselves.
Never feed them deliberately. The population is limited only by food, and adding more guarantees an explosion.
If you want fewer, feed the tank less and siphon the substrate. Numbers fall back within a few weeks without any other intervention.
Avoid: copper in anything, and avoid treating a population boom as a snail problem rather than a feeding problem.
Filtration and flow
Ordinary filtration is fine and they're unbothered by flow.
Keep the substrate reasonably clean with a siphon. Their burrowing helps, but it doesn't substitute for maintenance in a heavily stocked tank.
Hardness is the one water value that matters to them, and it matters for the shell rather than the animal.
With plants
Trumpet snails are entirely safe with plants and won't touch living tissue.
Their burrowing is mildly beneficial to rooted plants. It keeps the substrate from compacting into anaerobic pockets, which is a real problem in deep sand beds.
They can dislodge very newly planted stems while tunnelling, though established roots are never disturbed.
Health
They're close to indestructible. Shell erosion in soft water is the only routine problem, and it shows as a whitened, blunted tip.
An empty shell means nothing on its own — they're eaten by loaches, pufferfish and assassin snails, all of which leave the shell behind.
They survive conditions that kill most tank inhabitants, which is worth remembering: a tank where only the trumpet snails are thriving has a problem.
Breeding
They breed constantly and they don't need a partner. Trumpet snails are livebearers, producing fully formed young rather than eggs, and a single individual can start a population.
That combination — livebearing, self-fertile, substrate-dwelling — is why they're effectively permanent once introduced, and why they arrive so easily on plants.
Population control is entirely about food. There is no practical way to eradicate them short of stripping the tank, and in most cases there's no good reason to want to.
