Which saltwater fish is right for you?
Many of the species listed below are good beginner fish that perform well in group tanks.
The main consideration you should make if you are interested in protecting one of these species is whether or not they are compatible with the rest of the fish in your tank.
You will probably find that some breeds such as tangs, which are adequately found in local fish stores, should not be included in this article.
This is because they are more difficult to keep up with and require additional experience.
If you're just getting started in the saltwater passion, make sure you first gain some experience guarding hardy fish. Saltwater tanks require real water conditions, and while you can probably get away with small modifications to the water chemistry in a freshwater tank, this can be lethal in a saltwater tank.
