Does this product contain any zinc or copper?

I used these for snails. They provide extra calcium. I don't think there were metals at all. You may want to google the product to be sure

If I have a 3-4 gallon tank with a snail and a beta (and a moss ball) is it safe to break off a small piece of the wonder shell and use it?

You won't need to break the shell apart. These shells don't condition that much water. Here is what is printed on the back of the package: "For one-gallon bowls use 2 small shells. For 5-gallon aquarium use one large shell. For 10-20 gallon aquarium use one Super Size shell."

Can I crush these up and get the same effect

Hello, Thank you for asking. Actually Wonder Shells do a lot of different things for an aquarium. One of the things they do is make the water more hard. Now, I don't know what kinds of animals and/or plants you have, but if you smash a Wonder Shell up and add it to your tank all at once, there is a possibility that the water could become Way More Hard than will be healthful for your aquarium inhabitants. So I absolutely do not recommend doing so. They melt very nicely over time and do exactly what they are advertised as doing. Have Patience!! Patience is a virtue, right?

Will it be okay with tropic fish

In a word, "Yes!" In fact you know, most of the fish in the hobby really are relatively tropical. And I put these in every tank. Well, all the best to you!! :-)
