An aquarium has been one of the most interesting and beautiful decorations for your working or living space. Bringing a natural system to your home or office not only makes the space become more stunning but also gives you much comfort and relaxation when viewing.

A reef aquarium is among the most widely-used tanks over the years. It’s also considered a challenging type of aquarium to cultivate. This is because of the strict requirements for high water quality, excellent lighting, and filtration, etc. It is challenging to keep one but extremely satisfying to look at. Is that right? 

If you love the beauty of reef aquariums, keep reading this post to find out the best reef aquariums, as well as what to consider when having a reef tank. 

What is a Reef Aquarium? 

A reef aquarium is a marine tank that displays live corals and different marine invertebrates, as well as fish species that play a part in maintaining the tropical coral reef environment. 

A reef aquarium usually needs properly intense lighting, turbulent water movement, and more consistent water chemistry than a fish-only marine tank. Moreover, you need to carefully consider which reef animals are proper and compatible with each other.

What to Consider When Setting Up a Reef Aquarium?

Reef aquarium systems

With a little research, you can create a piece of the reef where critters live in harmony and, in many circumstances, will build a symbiotic relationship and help each other grow. The rapport of a clownfish and its host anemone is a typical example of this co-existence. The clownfish is safeguarded by the stinging tentacles of the anemone, while it gives the anemone food in the form of small fish that it obtains and the detritus that the clownfish deposits in the anemone. 

A reef aquarium system is a fish-only with livestock system with corals that need a highly high-quality lighting system and intensely high water quality and movement. A sustainable healthy reef aquarium also requires occupants that do not seriously affect corals, such as:

  • Reef-safe fish that do not eat invertebrates pick at corals and are not aggressive toward other fish species.
  • Reef safe invertebrates that do not eat corals. They are an essential part of a reef aquarium, setting it apart from a fish-only with livestock tank. 
  • Reef-safe tank janitors, when appropriately chosen, are great. They can decrease your tank maintenance chores to near zero. There are critters that can keep your aquarium glass clean, save your substrate from uneaten food and detritus, and will become fat in the process. 


As most corals cannot tolerate the levels of phosphates, nitrates, and other toxins that most fish species and invertebrates can withstand, water quality in a reef aquarium is the most crucial factor. Whereas most of the pricey state-of-the-art filtration systems work well at eliminating toxins, they are not by any means required. 

With the improvements in science and technology, mini reef aquariums have become more and more prevalent. Many reef tank aquarists invent their own reef aquarium filtration systems using one or a combination of various filters to achieve the desired results. 


As corals are added to a reef aquarium system, you must provide sufficient lighting for the corals. The generally accepted rule-of-thump for reef aquarium lighting is 3.5 watts per gallon of aquarium water for the majority of soft corals and 4.5 watts (of fluorescent light) per gallon of tank water for hard corals (SPS and LPS). 


Most corals need a high level of water quality and lighting, while there are easy ones that are less demanding, requiring a lower water-quality level or lower lighter level, enabling newbie reef aquarium keepers to achieve success. 

Some Types of Corals for Your First Reef Aquarium

1. Star, Green Star, and Daisy Polyps 

These perfect starter corals, often called Star Polyps, Green Star Polyps, and Daisy Polyps can tolerate both high and low-level light and an array of currents. These corals are sensitive to iodine and aluminum oxide in some phosphate-removing filter sponges, so you should cautiously consider putting these filter materials in your tank. 

This coral is very rapidly growing to the point where it can overgrow other corals. It should be blown clear of detritus occasionally to dodge filamentous algae and slime from getting a foothold. 

2. Finger Leather Corals and Colt Corals 

These are usually known as Finger Leather and Colt corals as they have projections like fingers that are round to cone-shaped and stubby. These thick finger-like projections grow from the very short and pale white stalk. While withstandable to most light and current conditions, these stunning corals are sought at mid-water levels in the ocean; therefore, moderate light and current levels are best for them in aquariums. 

3. Mushroom Corals 

The Mushroom (Actinodiscus) corals are soft ones, have no exoskeleton, and thrive on rocks. They might not grow well in bright lights or heavy currents. Mushroom Corals are best housed under low lighting conditions with little water movement to maximize expansion and reproduction.

Mushroom corals are safe with fish, motile invertebrates, and crustaceans. It would be best if you did not place them near other soft and stony corals and sessile invertebrates due to the harmful effect they can leave on them. 

4. Sea Mat and Button Polyps 

These corals can tolerate lower light but prefer bright light. Prefer moderate to heavy currents, Sea Mat and Button Polyps have an excellent reproductive rate and are aggressive. 

Some of these species leach out a potent neurotoxin that can affect humans (Palytoxin), which is toxic to other animals. You should wear gloves to handle them. Don’t touch them if you have cuts or open wounds on your hands, and remember to clean your hands after handling them. 

5. Moon, Pineapple, and Brain Corals 

These corals would prefer bright lights but are tolerant of much lower levels. They will attach to a substrate if not moved for some months. Users should be cautious because they can send out transparent sweeper tentacles at night to prevent other corals from growing near them. 

6. Toadstool Mushroom Coral 

They are excellent corals that adapt well to most lighting levels and low-to-moderate current levels. These corals spread rapidly and are considered great for propagation. They can release toxins that may affect stony corals and sea anemones. 

7. Zoanthids, Zoanthus Button Polyps 

Members of this coral are colorful, being shades of green and brown, but sometimes fluorescent red, pink, lavender, orange, gray, blue, or yellow, and usually two-toned. They create colonies of densely crowded polyps attached in a common tissue at the base. They love bright lights but can withstand lower lights.
