How to Identify the Marine Fish in an Aquarium

Maintaining a marine fish tank is a rewarding hobby. There are many different types of marine fish to choose from, but in order to ensure harmony in the aquarium, it is important to mix only compatible types of fish. To accomplish this, it is necessary to be able to identify the types of marine fish already in the aquarium.

• Use a digital camera to take pictures of the different fish species in the aquarium. Try to get pictures that show the coloration and markings of the fish as this will be beneficial when identifying them. Take note of the size and shape of the fish as well.


• Visit a fish store, and look at their selection of fish. Compare them to the pictures on the digital camera. Write down the names of any fish that match the ones in your aquarium.


• Conduct an Internet search for "types of marine fish." This should provide plenty of results to look through. Choose a reputable site for the most reliable information. Try to match the pictures of the fish in your aquarium to the ones on the site. Write down the names and any important facts or even print out the information for future reference.


• Purchase a fish guide from a local book store, pet store or online to identify any remaining fish. There are several comprehensive guides available that should be able to address all of your fish identification questions.


• Keep an updated list of all future additions to the aquarium to ensure that you are only mixing compatible fish.
