Also you can check plastic dip paint. It can be pealed off when it's dry.

Usage:

Animal and outdoor environment applications for PlastiDip protective coating include underwater acoustics, sharp edges, cable stems, cage floors, underground storage tanks, aquariums, iron bars, cable ties, crank baits, junction boxes, fishing sinkers, solder lugs, lobster and crab traps

Plasticdip would probably work very well to coat magnet to be used inside aquarium. I never tried it though.

Plastidip is great, but I have a can hear and it has a poison symbol on it. It also peels easy if it gets scratched. If your painting the outside of the back fusion or acrylic will work fine.
