Saltwater fish tanks have a reputation for being complex and too challenging for beginners. However, the reality is that it’s much easier these days. Owners can also make life easier for themselves by selecting the most appropriate species. In this guide, we’ll look at some of the easiest saltwater fish to care for. They’re typically hardy, undemanding, and less aggressive than other species. Remember: it’s essential to keep your tank clean regardless of the fish. Also, always quarantine new fish before introducing them to your aquarium!
1. Ocellaris Clownfish Are Easy to Feed
Everybody knows about clownfish because of the hit movie “Finding Nemo”. However, many people don’t realize that there are several varieties of this species. The ocellaris clownfish is the most iconic of these. They’re one of the most popular saltwater fish for beginners for several reasons. First, they have a beautiful appearance with their vivid orange and white coloring. They also do very well in bonded pairs and are relatively relaxed tank mates.
Most importantly for beginners, clownfish are very hardy. It’s very easy to find tank-raised ocellaris clownfish at licensed marine dealers. They’re perfect for a 20-gallon tank. They adapt very quickly and suffer from less stress than other species too. Another benefit is that they eat most marine food so it’s simple to provide for their needs. They prefer a water temperature of between 75°F and 80°F. You’ll also need a pH level of 7.8 to 8.4.
One quirk of clownfish is that they tend to stick to one area of the tank. Give them plenty of places to hide.
2. Yellowtail Damselfish Are Hardy and Adaptable
Another beautiful tropical fish, this species hails from the Caribbean and Indo-Pacific. They are extremely hardy as one of the healthiest fish species, so they’re very popular with new saltwater tank owners. The yellow damselfish is very adaptable, which makes it a good option for less experienced marine-life carers. However, there are a few points to be aware of before getting them. They’re very territorial, but it’s better to get three instead of one if you’re mixing species. This reduces their inclination to rule the roost.
Yellowtail damselfish eat algae, which can help keep the aquarium cleaner. They love hiding places, so include plenty of rocks and marine plants to enrich their lives. These fish grow up to two inches in length. A 20-gallon tank is suitable for a single fish, but you’ll need a larger one for multiple. They need temperatures of 72°F to 78°F and a pH level of 8.1 to 8.4.
3. Firefish Gobies Make Non-Aggressive Tankmates
Gobies are generally excellent beginner saltwater fish. The firefish goby is one of the most eye-catching because of its bright colors and dramatic dorsal fin. They have the dual advantage of a beautiful appearance and a hardy nature. The latter is particularly important for inexperienced owners because there’s more room to make mistakes! These fish grow up to three inches long and live for about three years in captivity. You should keep one in a 20-gallon tank but larger is advisable.
They’re peaceful tankmates so there’s little risk of them fighting with other species. However, take care because cichlids and other aggressive fish could attack them. Make sure you secure the tank’s cover because they can jump out of the water. It can take them time to adapt so don’t worry if you don’t see them for a few days after introducing them. They prefer an unlit, subdued environment. Feed them brine shrimp as part of an omnivorous diet.
4. Flame Hawkfish Are Resilient Bottom Dwellers
This hardy bottom dweller species is another fascinating fish. It’s suitable for beginners, but there are still some important points to consider. First, they’re larger than other species in this guide and can outgrow some tanks. They can reach up to nine inches long, so you’ll need a 40-gallon tank at a minimum. Flame hawkfish can also be aggressive toward their tankmates, especially fellow bottom dwellers. Don’t expect snails or shrimp to last for too long in an aquarium with these feisty fellows.
Nonetheless, they are very disease-resistant and crucially, are adaptable. Flame hawkfish prefer a pH of 8.1 to 8.4. The ideal temperature is 72°F to 78°F. The main problem some carers have with this species is that they can be picky eaters. They love crustaceans but may not want to eat conventional fish food. This is something you can experiment with through trial and error.
5. Yellow Watchman Goby Are Undemanding
The yellow watchman goby is a beautiful saltwater fish. They typically have a yellow-orange coloration with vivid fins. Beginners love them because they are hardy and undemanding. They are a long-term investment because they can survive for over a decade in captivity. These fish aren’t susceptible to diseases generally. However, they can contract marine velvet if you’re not careful.
They love eating brine shrimp and mysis shrimp as part of a carnivorous diet. Also, they have calm natures and don’t demonstrate aggressive behavior toward their tankmates. The only downside for some owners is that they’re quite reclusive. Yellow watchman gobies tend to hide frequently, so they’re not the most active fish. Many owners pair them with the Japanese pistol shrimp because of their symbiotic relationship in the wild.
6. Starry Blenny Keep Tanks Free of Algae
The starry blenny is another great fish that benefits saltwater aquariums. It’s larger than some of the other species on this list and will need a tank of at least 30 gallons. If you get a pair, you should have a tank of 50 to 60 gallons. The good news is that they’re another hardy species if you care for them properly. They do need a higher consistent pH level than the likes of clownfish. 8.1 to 8.5 is typical for these fascinating bottom dwellers.
Another benefit of the starry blenny is they’ll help keep the aquarium clear of algae. Their only major distinct dietary requirement is dried seaweed. They need plenty of rocks because they love hiding and grazing. These slender fish have a distinct appearance with their elongated bodies and tassels above each eye.
