Reaching an average length of two inches in captivity, Basslets are colorful, hardy, and generally peaceful, although they may become territorial. If more than one member of the species is added to the aquarium, add these fish simultaneously, as severe conflicts may arise. Offer these fish plenty of hiding places.
Most Anthias fish species are relatively hardy, but require food often in order to thrive in the home aquarium. Due to the complex social structure of Anthias, it is advisable to keep one specimen per tank.
Dwarf Angels are among the most colorful and popular of marine angel fish species. Growing to about four inches in length, these mild tempered fish adapt well to captivity and are compatible with many other species.
Large Angels are among the most popular fish for the home saltwater aquarium, and most marine angelfish adapt well to captivity. The diet of Large Angels consists of microalgaes, macroalgaes, sponges, and zooplankton. It is advisable not to introduce Angels from the same genus into one aquarium, as fighting will usually occur.
Blennies reach a size of three inches and are typically bottom dwellers. Blenny Fish are somewhat territorial in nature, and only one species per tank is recommended. Extensive rockwork and a good growth of microalgae are necessary to successfully maintain them in captivity.
Butterflyfish reach an adult size of six inches in captivity. The captive care of this group of fish varies a great deal due to the special feeding requirements (live coral polyp) of some species. A large tank with ample hiding places is needed to successfully maintain some species.
Boxfish reach an average size of three inches and adapt well to life in captivity if provided with plenty of rockwork and adequate swimming space. The diet of most Boxfish consists of sponges, tunicates, worms, and crustaceans. It is imperative to maintain Boxfish with peaceful tankmates.
The average size of most Cardinalfish in captivity is two inches. These fish make great additions to a peaceful aquarium, adapting well to life in captivity. Extensive rockwork and coral decorations should be provided to enable the fish to retreat from other tankmates. These fish can be bred successfully in captivity, and the fry can be raised to adulthood with appropriate care.
Chromis are related to damselfish and clownfish, but are typically less aggressive. They enjoy being in a school of three or more, and make a spectacular display in large numbers. Chromis are ideal fish for the reef aquarium, since they will not bother invertebrates and corals.
The average size of most Damselfish is two inches. They are often used to break in or cycle new aquariums. The majority of these fish are highly territorial, and may become aggressive toward other tankmates. They do well in groups of the same species. Click here to learn more about Damselfish.
Dottybacks, also known as Pseudochromis, are brightly colored, and reach a size of three inches. They are very hardy aquarium specimens that adjust well to captivity. Dottybacks feed on plankton, small crustaceans, worms and will accept most prepared foods. The aquarium should include a well-sealed lid, and plenty of rockwork and hiding places. Only one species should be maintained in an aquarium.
The average size of Clownfish is three inches and most are brightly colored with white stripes on the head or side of the body. This group of fish is extremely hardy, and is well suited to life in the average aquarium. Ideally, Clownfish should be purchased in small groups consisting of one species, and introduced to the aquarium simultaneously.
Most Filefish grow to around six inches and feed on algae and crustaceans. Filefish do extremely well in captivity and make ideal candidates for the average home aquarium. Provide Filefish with adequate hiding places and ample swimming space.
Gobies are relatively small fish, usually reaching three inches in captivity. Goby fish species adjust well to aquarium life. A well-sealed lid is a requirement for keeping gobies, as they will jump out of an open aquarium. Plenty of rockwork and the proper substrate of coral sand should be provided to enable burrowing or sand sifting Gobies the proper environment.
Most Hawkfish reach a size of three inches and are hardy specimens that adjust well to aquarium life. Keep in mind that while Hawkfish do well in reef aquariums, they will eat smaller shrimp and fish. A well-sealed lid and adequate hiding places are required to maintain these fish.
The size of these fish varies, but most members reach an average length of seven inches in captivity. Lions and Scorpions are hardy fish that adapt well to life in captivity. They usually prefer live foods in captivity, but some species convert to frozen foods quickly especially when young. Provide these fishes with ample hiding places and an appropriately sized aquarium for the species.
Rabbitfish, found in shallow lagoons in the Indo-Pacific and eastern Mediterranean, have small, hare-like mouths, large dark eyes, and a peaceful temperament, which gives them their name. They are colorful, and have well developed, venomous dorsal and anal fin spines.
Use caution when handling these fish, as the spines will inflict a painful sting. It is best to use two nets to corral these fish into a container, rather than a single net to transfer these fish. These fish are very hardy and disease resistant and make an excellent addition to a medium- to large-sized saltwater aquarium.
Rabbitfish are one of the few species that will eat problematic Bryopsis algae. Even though these fish are herbivores, use caution if they are to be housed in a reef aquarium, as they may nip at some corals and sessile invertebrates.
Tangs are commonly referred to as Surgeonfish or Doctorfish, and make a wonderful addition to the reef or fish only aquarium. If more than one species of Tang fish or sugeonfish is going to be kept, introduce different genera along with different-sized specimens simultaneously to limit aggression.
Triggerfish are very hardy specimens that adapt well to aquarium life if provided with a large tank and ample hiding places. Triggerfish reach an average size of six to ten inches in the home aquarium and often become very aggressive toward the same species and other tank mates. Smaller Triggers grow quickly, and are usually more docile in adulthood than if matured in the wild.
They are some of the most colorful of the moderately-sized saltwater fish that can be incorporated into a reef aquarium. Many of these wrasse fish species are very active by nature and are nearly always swimming out in the open, adding activity and beauty to either a reef or peaceful fish-only aquarium. Because of their diet in nature, these fish are ill-suited for a reef aquarium, as they will readily consume most crabs, snails and tube worms. The ideal aquarium will have plenty of live rock for hiding and a sandy substrate for burrowing into at night.
