The Aquascape Faux Log Fish Cave provides pond fish, such as goldfish and koi, shelter from herons and other pesky predators. The natural-looking faux wood design blends well into any setting and can be used for indoor or outdoor use. Add to existing ponds, new ponds, or use as a decorative accent in the garden. The heavy-duty, polyresin construction is built to last and stand up to the elements. 19"L x 12"W x 10"H
