I love the martini glass idea! I went out to buy some right after I read this thread(as well as some glass stones to put in them. Now I'm trying to figure out how to make a fake toothpick with olives (especially one that won't tear fins).
I also have plastic coconut cups that I got at a party store years ago. I filed down the rim because it was a little rough. The opening is sorta wide so i put a plant of to one side of the opening to block it a little and make the fish feel a little more hidden.
I was also thinking that a picture frame (just the empty frame, no pictures or glass) leaned against a wall would look neat.
