How many fish can I put in a 30 gal saltwater tank is a common question asked by new aquarium owners? With the growing popularity of saltwater aquariums more and more people are venturing into the hobby. Most of these people seem to gravitate to smaller systems under 40 gallons mainly for cost reasons.

While small tanks maybe affordable they can also severely limit your fish choices due to the nature of many marine fish.First you have to realize the saltwater fish are not like freshwater fish. They are territorial and some will protect that territory to the death.

With that in mind you will need to provide your marine fish with ample room to call their own. As a very basic rule of thumb you can have one small fish per 10 gallons of tank volume. This is dictated however by the tank shape and fish type.

Tips For Adding Fish To Your Tank

  • A critical step in stocking a smaller saltwater aquarium is to research your fish choices before you shop, never impulse buy saltwater fish! Once you see some fish that you like you can dig further into their characteristics and see how they may get along with other tank mates.
  • Do not let size fool you, some of the most brutal and violent fish are small. Fish like some dottybacks and damsels will attack fish twice or even three times their size, and often times kill them in the process.
  • If you feel one of your choices maybe a little aggressive you may want to add them last. Often times adding a semi aggressive marine fish last will eliminate some of the territory battles that can take place. It is not guaranteed to work this way though because fish like people have different personalities.
  • A good saltwater aquarium guide will be able to help you determine the types of saltwater fish you can keep in a smaller tank. Then you will want to go to the local fish store and see them in person and see if they look and behave how you want.
