Remember to measure for the perfect fit. With the Zoo Med Floating Aquarium Log Reptile Hideout， you can add a natural touch to your aquatic pets’ habitat. This log floats at just the surface， so your fishy friends can swim inside. The bottom weighting prevents it from rolling over if newts or mudskippers climb on top. The log provides security， comfort and stress reduction for your little friends， and a feeding hole lets you interact with your pets.
