Excellent all around. Buy the largest size for aquariums with a school of copies, but they love it.

This hide really works well for my aquarium! I have a 30 gal and so far it’s great! The only hitch was getting it into the substrate, but that was due to my having plants that needed planting and I couldn’t wait for the hide. But it looks great and it stays submersed well.
