Multi-ingredient bottom tablets for everyday feeding of aquatic turtles (including pond turtles) kept in aquaterraria. A wide range of carefully selected ingredients meets all the dietary requirements of turtles. The tablets are also exceptionally palatable, hence eagerly eaten by the turtles. REPTOTABIN contains the addition of easily assimilable calcium and phosphorus derived from marine fish. The right proportion of those two compounds ensures good assimilability of calcium. Calcium metabolism is also supported by the content of vitamin D₃. Optimal levels of calcium, phosphorus and vitamin D₃ together with their optimal mutual proportions ensure proper shell and skeletal development and prevent deformations.
