I seen some of these on the internet, they look really cool, and would be great for the aquarium, provides plenty of hiding spaces. I was wondering are Lok Rocks any good? Please let me know.
they're crap....
i used them and the lil ledge/shelves. they are made of crappy plastic that has sharp edges and you really are limited to the formations you can make.
I had those like 10 years ago and I think they still in a box of aquarium crap gone wrong. I didn't like them either. Thought they looked fake and kept getting knocked over.
