What is Reddit's opinion of Exo Terra Sepia Bones for Turtles?
From 3.5 billion Reddit comments

By popularity on Reddit, this product is:

#90 in Reptile & Amphibian Food

#65 in Exo Terra

#18 in All Reptile

But...any cuttlebone should be fine. Any pet store should have them because birds need them as well.

Turtles need them for additional calcium (females need them even more because they're larger and they produce eggs).
