Triangle Rabbit Snail (Tylomelania sinobartfeldi)

The Triangle Rabbit Snail is a rare freshwater snail from the rivers of Sulawesi, Indonesia, recognized for its distinctive angular “triangle-shaped” shell, dark coloration, and signature rabbit-like facial tentacles. Although smaller than some of its larger Tylomelania relatives, it shares the same elephant-like facial features and gentle personality. Calm, active, and visually striking, it makes a functional and exotic addition to planted aquariums and shrimp tanks.

How They Help Your Aquarium

Triangle Rabbit Snails are peaceful grazers and natural clean-up crew members.

• Graze on algae, biofilm, and detritus
• Help keep substrate and hardscape clean
• Eat leftover food before it breaks down
• Completely plant-safe and shrimp-safe

They work slowly and steadily, making them ideal for mature, stable tanks rather than brand-new setups.

Care & Tank Requirements

Triangle Rabbit Snails prefer warm, mineral-rich water and consistent conditions. They’re hardy and beginner-friendly once established.

Tank Size

• Minimum: 5 gallons for a single snail (since they're smaller than other rabbit snails, they can be housed in nano tanks)
• Recommended: 10+ gallons for long-term stability or small groups

Water Parameters

These snails thrive in slightly alkaline, mineralized water similar to Neo-style or Sulawesi setups.

• Temperature: 74–86°F (24–30°C)
• pH: 7.0–8.5
• GH: 6–15
• KH: 2–8
• TDS: 100–300 ppm

Calcium and minerals support strong shell growth. Very soft or acidic water may cause shell wear over time.

Setup Notes

• Soft sand or fine gravel substrate
• Provide driftwood, smooth rocks, and calm grazing areas
• Gentle to moderate flow with good oxygenation
• Avoid aggressive or snail-nipping fish

Diet

While they graze naturally throughout the aquarium, Triangle Rabbit Snails benefit from supplemental feeding.

They eat:

• Algae and biofilm
• Invertebrate or algae wafers
• Shrimp/snail pellets
• Decaying plant matter
• Blanched vegetables (zucchini, spinach, kale)
• Occasional calcium-rich foods or cuttlebone

Feed lightly and remove uneaten food to maintain water quality.

Breeding Information

Triangle Rabbit Snails reproduce slowly compared to common pest snails.

• Livebearers that produce one fully-formed baby at a time
• No larval stage
• Very slow, controlled reproduction
• Breeding occurs naturally in stable, mineral-rich tanks

This makes them suitable for aquariums where population control is important.

Compatibility

Triangle Rabbit Snails are peaceful and community-friendly.

Compatible with:

• Neocaridina shrimp
• Amano shrimp
• Small, peaceful community fish
• Other non-aggressive snails

Avoid loaches, puffers, crayfish, cichlids, or species known to nip tentacles.

Why Choose Triangle Rabbit Snails?

• Distinctive angular “triangle” shell shape
• Peaceful, shrimp-safe, and plant-safe
• Small so can be held in small tanks
• Slow reproduction with live birth
• Excellent natural grazer and scavenger
• Unique Sulawesi species with exotic character

If you’re looking for a rare, visually unique rabbit snail that adds both function and personality, the Triangle Rabbit Snail is a standout addition to a well-maintained aquarium.

These have some imperfection in the shell, they are about 3/4 of an inch and don't get much bigger than a dime when full grown.
