Tarebia granifera, (Spike Tail Trumpet Snail, Quilted Melania), is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Thiaridae. This snail is native to south-eastern Asia. The maximum height of adult shells of this species is from 18.5 mm to 25.1 mm, some can reach up to 35 mm. Our form of Tarebia granifera has a brown body whorl and a dark spire. These snails are peaceful and solitary; will not engage with tankmates.
Tarebia granifera colonize different types of habitat, from rivers, lakes and irrigation canals to concrete lined reservoirs and ornamental ponds. Many of these habitats were vegetated and the associated vegetation included many types of emergent monocotyledons and dicotyledons. It favours turbulent water and tolerates some current. Typically most of these snails are buried in the sediments and are not visible from the surface. This species will tolerate water temperatures from 15°C to 30°C without any problems.
Tarebia granifera is both parthenogenetic and ovoviviparous, although males have been reported. Most Tarebia granifera are clones of the female parent. Embryos develop in a brood pouch. This pouch is a compartmentalized structure lying immediately above the oesophagus and develops only after the snail has reached maturity. Its size expands as the number of embryos increases. Tarebia granifera has 1 – 77 embryos in its brood pouch. The female can give birth to one juvenile every 12 hours. Young snails emerge through a birth pore on the right side of the head. The newborn shell is <1–2 mm in height with between 1.5 and 4.8 whorls. The size of juveniles at birth is 0.7 – 2.1 mm. These newborns have a high survival rate in the field.
Attainment of sexual maturity in Tarebia granifera is generally indicated by the size of the smallest snail observed to give birth rather than a histological assessment of the development of the gonad and associated reproductive structures. Estimated onset of maturity is at 7 – 12 mm shell height, reached at an age of about five months.
Recommended water parameters are: the average keeping temperature 18°C – 26°C, pH 6.0 – 8.0, hardness 8 – 20 dGH. Diet: Other than algae and waste, Tarebia granifera eat invertebrate pellets, flake foods, and cooked vegetables (such as zucchini, kale, spinach, or cucumber). Avoid any food product, medication, or plant fertilizer that contains copper of any form. Copper is toxic to invertebrates. Many commercial fish foods, medications, and plant fertilizers contain copper or more commonly copper sulfate. Always look at the ingredient list for any product going into the aquarium to ensure they are copper free.
