Saim Aquarium Ceramic Rock Cave Shrimp Shelter Fish Tank Ornament Breeding Hiding Spots Holes

This definitely works to keep other fish from getting to your shrimp or snail food, but my Gourami fish has harmed himself trying to get to the food. He has rubbed all the flesh off his own forehead trying to get through the holes. It is a terra cotta type material and has rough edges where the holes are. Silicone would be much better to prevent injury to your fish.
