Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.

Does salt help heal fish?

AQUARIUM SALT promotes fish health by improving gill function, making it easier for fish to breathe. It also provides essential electrolytes that fish need to reach peak coloration and vitality. These electrolytes may be lost each time you perform a partial water change, and will need to be replenished.
