Before you decide on an aquarium with saltwater fish, learn the acclimatization process well. Here are the descriptions of some common saltwater fish that you can purchase for your aquarium:
In captivity, the average size of Butterfly fish is six inches. The care of these fish can be rather difficult because of the feeding habits of some species as they exclusively feed on live coral polyp.
The cardinal fish adapt well to captivity and grow up to two inches in length. They do need extensive rockwork and other decorations so that they can retreat from the other members of the tank when the please.
The Goby fish species adapt well to life in captivity and aquarium. They reach an average length of three inches. A sealed aquarium will be required if you want to keep these fish as they have a tendency of jumping out.
These are high maintenance fish which when kept in captivity need to be fed frozen squids which have been vitamin enriched, live ghost shrimp, and similar meaty foods. After the Rays have settled down in the aquarium, it is advisable to regularize and control the amount of the food that is offered to the fish.
Seahorses usually face difficulty in competing for live food with other fish, and hence, it is advisable to keep the seahorses in separate tanks. They can be fed frozen squids which have been vitamin enriched, live ghost shrimp, and amphipods.
The Sharks that are suitable for aquariums are usually found around the rocky reefs, coral reefs and lagoons. They need to be fed frozen squids which have been vitamin enriched, live ghost shrimp and similar meaty foods.
The ideal aquarium for this variety of fish would be a larger sized aquarium of about 70 gallons in size that is well sealed along with plenty of rockwork and overhangs. Their diet includes smaller fish, planktons, and small invertebrates.
The Trigger fish grow between six and ten inches in length and adapt well to life in an aquarium if provided with ample swimming space and hiding places.
