Reef Aquarium Fish Selection
Table of Contents
Many species of fish can be used in a reef aquarium tank. The most common fish found in an aquarium tank are centropyge (angelfish), amphiprion (clownfish), dragonnettes, mandarinfish, gobies, tangs or surgenonfish, among others.
The common rule of thumb when integrating fish into a reef aquarium is to understand that reef tank creatures are survivors by nature and not all fish will live in harmony and that you may have to remove certain fish that are harming the coral or other inhabitants of the tank.
Centropyge, known as angelfish, are generally a good choice for reef aquariums, especially larger tanks. There are a number of centropyge varieties. The genicanthus melanospilos (Japanese Swallowtail Angelfish) is known for its gentle nature and as a fish that will not disrupt corals or invertebrates. Some common types of centropyge include centropyge bispinosus (Coral Beauty Angelfish), Centropyge fisheri (Fisher’s Angelfish), Centropyge loriculus (Flame Angelfish), Centropyge flavissimus (Lemonpeel Angelfish), Genicanthus personatus (Masked Angelfish), Centropyge multicolor (Multicolor Angelfish), Centropyge eibli (Orangelined or Eibl’s Angelfish) and Centropyge potteri (Potter’s Angelfish).
Amphiprion, otherwise known as clownfish, are also a common fish in reef aquariums. The Amphiprion ocellaris is considered an excellent choice for reef aquariums. Their vivid orange color with characteristic white striping makes them a recognizable fish among reef aquariums. Most amphiprion make good choices for reef aquariums perhaps with the exception of Maroon Clownfish that can grow very large and act aggressively.
The algae eating creatures, gobies, are also safe for reef aquariums. They also usually eat amphiphods and copepods. Gobies are usually categorized in three groups: sand sifting gobies, shrimp goides and small gobies. Some of the common sand sifting gobies are Valencienna puellaris (Diamond Watchman Goby), Engineer Goby (Pholidichthys leucotaenia) and Amblygobius decussates (Orangemarked Goby). Among the shrimp gobies there are lots of species including the rarely aggressive Amblyeleotris diagonalis (Diagonal Bar Prawn Goby) and the passive Stonogobiops nematodes known as a Blackray Shrimp Goby. There are many different species of small gobies, as well, and they are known for not interfering with the invertebrates. Some common species are Elacatinus horsti (Gold Line Goby), Gobiodon okinawae (Yellow Clown Goby) and Paragobius lacunicolus (Panda Clown Goby). Small gobies come in a multitude of colors and are mostly bullet-shaped smaller fish.
Another algae-eating fish that are great for reef aquariums are surgeonfish, known as tangs. They are herbivores by nature so they will also not eat the corals or invertebrates. They can grow to be pretty large, which makes larger tanks a better fit for them. Tangs are very bright and colorful fish. There are dozens of tang species and some of them include Acanthurus Achilles (Achilles Tang), Paracanthurus hepatus (Pacific Blue Tang), Acanthurus lineatus (Clown Surgeonfish), Zebrasoma xanthurum (Purple Tang) and Ctenochaetus hawaiiensis (Chevron Tang).
Navigating the Vibrant World of Reef Aquarium Fish Selection
Diving into the world of reef aquariums is akin to embarking on a colorful, underwater adventure right in your own home. The selection of fish is a critical step, not just for the aesthetic appeal but for maintaining a healthy and thriving ecosystem. With an array of species, each with its unique needs and behaviors, the task can seem daunting. Yet, with a bit of know-how and an eye for detail, anyone can curate a vibrant aquatic community.
Understanding Fish Compatibility
Choosing Peaceful Community Fish
When starting your reef aquarium, consider species known for their peaceful nature, which can coexist without territorial disputes. Fish like the Ocellaris Clownfish (Amphiprion ocellaris) or the Royal Gramma (Gramma loreto) are excellent choices. They not only bring a splash of color but also adapt well to life in a community tank. It’s essential to research their habitat needs, such as hiding spaces and tank size, to ensure they thrive.
Avoiding Aggressive Species
While some may be tempted to include more aggressive species for their unique colors and patterns, it’s crucial to understand the risks. Aggressive fish can stress or harm other tank inhabitants, leading to a disrupted ecosystem. Species such as certain Damselfish or large Angelfish might dominate smaller, more peaceful fish, leading to an imbalanced aquarium.
Habitat Requirements and Tank Size
Tailoring the Environment to Your Fish
Each species in your reef aquarium will have specific habitat requirements, from water flow and temperature to substrate and hiding places. For instance, the Yellow Tang (Zebrasoma flavescens) requires ample swimming space and algae-rich surfaces to graze on. Creating a habitat that mirrors their natural environment is key to their health and happiness.
The Importance of Spacious Living Quarters
Tank size plays a pivotal role in the wellbeing of your aquarium inhabitants. Overcrowding can lead to increased stress, aggression, and disease. A larger tank provides more stable water conditions, which is crucial for sensitive species like the Mandarin Dragonet (Synchiropus splendidus), known for its vivid colors and intricate patterns.
Nutrition and Feeding Practices
Understanding Species-specific Dietary Needs
Nutrition is a cornerstone of a healthy reef aquarium. Each fish species has its dietary preferences, ranging from herbivores that graze on algae to carnivores that require a diet of meaty foods. For example, the Flame Angel (Centropyge loricula) benefits from a varied diet of algae, mysis shrimp, and specially formulated pellets to maintain its vibrant coloration.
Sustainable Feeding Strategies
Overfeeding is a common mistake that can lead to water quality issues. Implementing a feeding schedule that mimics natural feeding habits can prevent overfeeding and ensure all fish get their necessary nutrients without polluting the tank. It’s also an opportunity to observe your fish, ensuring they are healthy and active.
In conclusion, selecting the right fish for your reef aquarium involves a blend of aesthetic preferences, behavioral compatibility, and environmental considerations. By focusing on peaceful community fish, tailoring the habitat to their needs, and providing proper nutrition, you can create a harmonious and stunning underwater world. Engaging with your local aquarium community and continuing to educate yourself will further enrich your reef-keeping journey.
FAQs on Reef Aquarium Fish Selection
What are the best fish to start with in a reef aquarium? Starting with hardy and peaceful fish like the Ocellaris Clownfish or the Royal Gramma is advisable. These species are less likely to cause disruptions in the tank and can adapt well to a variety of conditions, making them perfect for beginners.
How do I know if a fish is compatible with my current aquarium inhabitants? Research is key. Look into the temperament, size, and dietary needs of the fish you’re interested in. Ensure they won’t outgrow the tank or prey on smaller species. Fish with similar habitat requirements and non-territorial behavior are generally good choices for community tanks.
Can I mix large and small fish in the same tank? While it’s possible, caution is necessary. Larger fish can sometimes see smaller fish as prey. It’s important to choose species known for their peaceful nature and ensure there’s ample space and hiding spots for smaller fish to retreat to.
How often should I feed my reef aquarium fish? Most reef aquarium fish thrive on being fed once or twice a day. It’s crucial to adjust the amount of food based on the number and size of fish to avoid overfeeding. Observing the fish during feeding times can help gauge the right amount.
What should I do if I notice aggression in my tank? First, try rearranging the tank’s layout to disrupt established territories. If aggression persists, you may need to remove the aggressive fish or provide additional hiding spaces for the more peaceful species. Monitoring your tank’s dynamics is essential for maintaining harmony.
