How to Choose Your Fish for a Saltwater Tank

Learn to fill your new saltwater tank with fish that will survive and thrive

Picking fish for a saltwater tank is fun, even if you don’t know exactly what you want.  Saltwater fish are very interesting and different from freshwater fish.  By learning just a few basics, you’ll be able to make the best choices for your new fish for a saltwater tank.

Understand the Species

Picking fish for a saltwater tank can depend highly on your personality.  While you may know which fish you like and want, other characteristics must be evaluated BEFORE you buy fish for a saltwater tank.  You need to learn about each species’ compatibility behavior, particular characteristic traits (personalities), dietary requirements, feeding habits, and growth and mating patterns. 

Another thing you must keep in mind is the number of fish you wish to buy.  Before buying many fish, you should research the types, their compatibility, and how much space is required for each fish.  Some fish will prey on others and some will be more aggressive. 

Compatibility Counts

It is very important to make your selections of fish for a saltwater tank keeping compatibility issues in mind.  Whether you’re getting fish for a “fish only” tank or for a reef system, you must know about the personality of the fish you choose.  Some fish are more “community oriented” than others.  Choosing fish that don’t get along well with other life in your tank can mean disaster. 

Several types of aggressive behaviors contribute to whether the fish you choose will be compatible.  The basic types are predator/prey, territorial protection, mate protection, spawn protection, and feeding behavior.  A few examples:

You don’t want to add a single Angelfish or Jewelfish to a mated pair.  The fish of the same sex will go after each other. 

Keeping larger fish like Lions, Snappers, and Groupers with small fish like angelfish and damselfish is not suggested.  The larger fish will perceive the small fish as prey and attack. 

Harassment will most likely occur whenever you put a new fish into an established aquarium.  Usually it doesn't seem to matter what the type or species of fish.  Once the initial phase is over, the members of your tank will adjust and return to normal.

The Best Beginner Fish for a Saltwater Tank

Fish can vary in price anywhere from three dollars to two hundred or more.  Giving fish enough room to grow a couple of inches in the tank might also be necessary. Consider cheaper fish for your first set of fish for a saltwater tank. Cheaper fish like Gobies, Damselfish, and Clownfish.  This way if something goes wrong your first time around you won’t loose a small fortune in fish.

Your initial choice of fish for a saltwater tank, will most likely determine your satisfaction with a saltwater tank.  Take your time and choose carefully for years of enjoyment.
