Are saltwater fish hard to keep? Are they harder than freshwater?
Saltwater fish only tanks are about as easy as keeping a freshwater fish tank. The major difference is knowing how to maintain the salinity. However, saltwater reef tanks require a bit more knowledge. Corals require better light and the addition of trace elements to the water to be healthy. As with any other type of aquarium, you need good equipment and you need to maintain your tank properly through monthly water changes and proper animal husbandry.
