Aquarium safe magnets?

[Becca]

So, does anyone know how to tell if a magnet is aquarium safe? Amazon has loads of different types of craft magnets, but I'm not sure which might be safe.

I'm thinking of re-doing the moss wall in the 33 because there are some aspects of my original design I'm not happy with and the suction cups holding it up are failing. I was considering using magnets at least for the inner-most portions of it (where the kids can't reach), rather than just suction cups. Of course, I want something that isn't going to rust away or harm fish/shrimp, but will hold in place.

I have read that people sometimes cover the magnets in fish/food safe epoxy.

That thought crossed my mind. I may just go with suction cups, the more I think about the odds of one of my kids eating a magnet...

Yes, I saw those! I'll need to mull it over. It will be at least a week before I can even think about tearing that thing down and rebuilding it, given the time it will take.

Or you can encapsulate them in silicone.

Hmmm... those are pretty cool. I enjoyed looking at the video on this page:

There are a lot of possibilities.
