i want to make a natural looking vivarium, but the only thingh i can come up with to shape it with is black waterfall foam at my local nursery. it is supposed to be safe for fish, and i think i could press coco bedding on it to male it look natural.
i am wondering if anybody has used this before. will it adhere to glass, or should i make th mold so i can remove it from the tank? any feedback is helpfull!!!
-Thanks
