Orange Poso Rabbit Snail
Tylomelania gemmifera
📍 Poso Lake, Sulawesi, Indonesia
The Orange Poso Rabbit Snail is a striking freshwater snail native to Indonesia, known for its vibrant orange coloration and distinctive elongated shell with prominent spiral ridges. These peaceful detritivores are excellent algae eaters and biofilm consumers, making them valuable additions to established aquariums. They are moderately hardy but require stable water parameters and should not be kept with aggressive fish or puffers.
Care Guide
Diet
Orange Poso Rabbit Snails are primarily detritivores that feed on biofilm, algae, and decaying organic matter. Supplement their diet with blanched vegetables (zucchini, spinach), algae wafers, and quality sinking pellets. They prefer established tanks with mature biofilm but will accept commercial snail foods.
Behavior
These snails are nocturnal and spend most of the day hidden among plants and substrate, becoming more active at night. They are solitary or can be kept in small groups and move slowly across surfaces while grazing. They are sensitive to water quality changes and may retreat into their shells if stressed.
Breeding
Orange Poso Rabbit Snails are ovoviviparous (live-bearing) and do not lay eggs like most freshwater snails. Females produce small numbers of fully-formed juveniles, making population control less of a concern than with egg-laying species. Breeding in captivity is possible but not guaranteed without optimal conditions.

Common Diseases
Shell Erosion
Pitting, thinning, or dissolving shell surface; rough texture on shell
Increase water hardness (calcium/magnesium), maintain pH above 7.0, perform regular water changes, add cuttlebone or calcium supplements
Parasitic Flukes
Excessive mucus production, lethargy, shell damage, refusing food
Quarantine affected snails, perform frequent water changes, treat with anti-parasitic medication (avoid copper-based treatments), maintain optimal water quality
Bacterial Infection
Discolored patches on shell or body, foul odor, tissue decay, inability to retract into shell
Improve water quality immediately, increase aeration, perform 50% water changes daily, remove decaying food promptly, consider antibiotic treatment if severe
Copper Toxicity
Lethargy, shell damage, inability to move, death
Immediately move snail to copper-free water, perform large water changes, avoid all copper-based medications and fertilizers in snail tanks
