Malaysian trumpet snail care guide

Also called: MTS, Red-rimmed melania, Trumpet snail

Malaysian trumpet snails are small, cone-shelled snails that burrow in sand by day and eat leftovers and algae at night. They are very hardy and harmless to plants and fish, but they give birth to live young and can multiply fast if you overfeed.

Malaysian trumpet snails need a tank of at least 10 gallons (38 L), and water at 20–27°C (68–81°F) with a pH of 6.5–8. They grow to about 2.5 cm (1 in) and are peaceful.

Tank setup

A small group does well in a tank of 10 gallons (38 L) or more. They spend the day buried in the substrate and come out at night. Soft sand is best, since coarse gravel or sharp pebbles can injure their shells. Cover filter intakes with a sponge so young snails are not pulled in.

How many Malaysian trumpet snails in a tank?

The smallest common tank that suits Malaysian trumpet snails is a 10 gallon. Here is roughly how many fit in each size when they are the only fish, based on adult size and waste output. Leave room if you want tank mates.

Water parameters

Keep them at 20–27 °C (68–81 °F), pH 6.5–8.0 and 6–15 dGH. They are hardy and cope with a wide range of conditions, and they can even adapt to slightly brackish water. Hard, slightly alkaline water keeps shells strong, while acidic water slowly pits them. Avoid copper medicines and be careful with plant fertilizers.

Feeding

They eat leftover fish food, soft algae, biofilm and decaying plant matter. In most tanks they find enough food without extra feeding. If numbers drop or shells look thin, add an algae wafer or calcium-rich snail food now and then.

Behavior

Peaceful and mostly nocturnal. Their tunnelling stirs up the substrate and mixes waste down to plant roots, which helps stop stagnant spots forming. They don't harm plants, fish, shrimp or other snails. Assassin snails, pufferfish, clown loaches and some large cichlids will eat them.

Breeding

They breed on their own and very quickly. Females can have young without a male, carry them in a brood pouch and release tiny, fully formed snails, sometimes dozens at once. Numbers rise and fall with food, so a large population usually means too much feeding.

Tips from experienced keepers

  • Feed less if numbers explode. The snail population follows the food supply.
  • Trap extras after lights out: leave a slice of blanched vegetable on the sand, then lift it out with the snails on it.
  • Rinse plants and used gravel well. These snails can survive out of water for one to three weeks in damp gravel.
  • Never release them or tank water into ponds or streams. They are invasive in many countries.
  • Choose sand over coarse gravel so their burrowing doesn't scratch the shells.

Frequently asked questions

Are Malaysian trumpet snails good for an aquarium?

Yes, in moderation. They eat leftovers, turn over the substrate and don't harm plants or fish. The only downside is that they breed fast when there is plenty of food.

How do I get rid of Malaysian trumpet snails?

Feed less, vacuum the top layer of substrate and trap them at night with a piece of vegetable. Assassin snails also hunt them, but don't add those if you keep other snails you want to save.

Do Malaysian trumpet snails eat live plants?

No. They eat algae, leftover food and leaves that are already dying. They are one of the safest snails for planted tanks.
