A small pod for small aquatic animals! My shrimp and betta fish both enjoy this hide. I use it for my shrimp but my betta likes to hang out in it too! For added enrichment, I like to hide food in the pods for my aquatic pets to find. Width - 1.75 inches Height - 1.5 inches All J&L Exotics aquarium supplies are made from a safe material called PETG. While safe, it is important to maintain cleanliness of the item. If algae builds up, I like to scrub them with a clean toothbrush!
