I'm redoing my 60g a bit (48×12×24) and I'm looking for a decoration that would be a good hiding place for my 5" goldfish, but one that will also fit into the 12" width. It's a common goldfish, so rather slim bodied if that helps. Also any other recommendations for hiding spots for the amanos in there, the goldfish doesn't bother them, they're just shy. Right now they have a little rock pile and a pirate ship they hang out in, but I'm looking to spruce it up a bit. And something that a mystery snail won't get stuck in.
