Marine fish is more easier to take care of compared to Saltwater fish. Saltwater fish requires stable conditions in order to survive. However, marine fish is difficult to maintain compared to freshwater fish. If you’re just a beginner in the aquarium hobby, it’s better to choose the right fish to begin with. And your best bet is having “easy” marine fish to fill in your tank. In this article, we’re going to tackle 6 easy marine fishes that you’ll probably love to take care of.

  1. Ocellaris Clownfish

  • This fish is easy to keep and carries a brilliant orange coloration. Ocellaris Clownfish become popular after the success of the 2003 movie “Finding Nemo”. They can adapt to any kinds of aquariums no matter big or small. They are tank breed which makes them easier to take care since they can withstand a range of conditions. Ocellaris Clownfish are also easy to feed since they are omnivorous. They are less likely to experience stress since they are used to captivity and being transferred from one environment to another. They can grow up to 3 inches in size but some of them can only get larger up to 2 inches only. They are reef safe, which makes them an excellent choice if you decided to upgrade on putting a reef inside your aquarium. The Ocellaris Clownfish are also mindful of their surroundings so rest assured that your corals are safe and won’t be eaten by them.
  1. Blue Green Chromis

  • The Blue Green Chormis is the best marine fish to get if you’re on a budget. It can be purchase for as little as $5 in your local fish store. Just like the Ocellaris Clownfish, the Blue Green Chromis is reef safe so rest assured that your corals are safe. It can also adapt to different conditions which makes them the perfect choice for beginners. It can be hard to maintain salinity and pH levels at a stable state when you’re just a beginner. However, you don’t have to worry because the Blue Green Chormis can withstand mild and major changes in such conditions.
  1. Cardinalfish

  • The Kauderns Cardinalfish and Pajama Cardinalfish are both excellent choices for a beginner like you. It’s important to look for the captive bred varieties of this type of fish. Captive bred suffer from significant stress as they are not used to travel. Wild varieties should be definitely avoided too since they are hard to keep. Keep in mind that the Kauderns Cardinalfish can be slightly aggressive towards other fishes, so putting them in larger aquariums is a must. However, Pajama Cardinalfish are more docile and can be kept easily in a small aquarium. Just like the first two fishes in this article, both of these cardinalfishes are reef safe so you don’t have to worry about your corals.
  1. Damselfish

  • There are a wide range of Damselfishes you can find including the Azure Damselfish, the Yellowtail Damselfish, and the Rolland’s Damselfish. They are omnivorous, small, and most importantly, reef safe. They are best kept in a tank which can yield 30 gallons of water or more. They can be aggressive especially when brooding. They won’t do well with long finned fish. However, they’re fine when mixed with other clownfish, cardinalfish, and chromis. It’s recommended to keep damselfish into small groups and maintain odd numbers of the species. They originated from Indo-Pacific reefs and can be very active both day and night.
  1. Blenny

  • Blenny fishes such as the Midas Blenny, Sailfin Blenny, Tail Spot Blenny, Bicolor Blenny, and Linear Blenny are popular due to their interesting appearance and swimming skills. They spend most of the time lurking on rocks or resting below the aquarium gravel. Almost all of them are peaceful and reef safe. They can also grow up to 5 inches upwards so larger aquariums are definitely needed if you plan to add them to your collection.
  1. Wrasse

  • Wrasse are colorful and very attractive which makes them interesting to watch as they swim around in your aquarium. However, they can be aggressive towards other fishes and you should definitely keep them along with slow, long finned species. Wrasses likes to hide and swim between live rocks and crevices. They also require a high protein omnivorous diet in order to match their natural diet. Recommended Wrasse for beginners include Red Head Solon Fairy Wrasse, Lubbocks Fairy Wrasse, Ruby Head Fairy Wrasse, Six Line Wrasse, Carpenters Flasher Wrasse and the McKosckers Flasher Wrasse. They are also sexually active and you’ll find them consistently dating around the aquarium to multiply as many as they can.
