Today, I went to Lowe's to get some kind of tubing to use as a hiding place for my tire track eel and my senegal bichir, since the tt eel has outgrown most of its existing hiding places. I ended up getting this piece of rubber tubing, but I have no idea whether it is okay to put in my aquarium.
Do you all think that this is aquarium-safe? If not, is ther any way to make it aquarium-safe (like soaking it in water or something)? Any comments/suggestions will be greatly appreciated.
