I have noticed in multiple threads that almost no one has any kinds of hides for the poly's in their setups. Alot just have substrate and a completely open tank. Just curious why this is? Do polys not appreciate or make much use of large caves or hollow log ornaments etc? Or it just because these kinds of hides are sometimes ugly to look at? I understand that alot of members utilize plants and driftwood which looks really good and natural and provide some cover but it doesn't always allow the poly's to completely hide from view. What is everyone's thoughts on this topic?
