We will tell you some of the species of fish that we can have in our aquariums. We will start by talking about the fantail or fan tail.
El fantail or fan tail It is a fish that belongs to one of the Goldfish varieties. It should be noted that in many shops you see Goldfish with a double tail fin and dorsal fin that are called Fantail Goldfish, but to be of quality they must have some special requirements. All his fins They must be short, with a double caudal fin that measures between ¼ and ½ of the body depth, and it must also have two anal, pectoral and abdominal fins.
Another variety of Goldfish is the Fringetail or Fringe Tail. Its body is more robust with a particular egg shape. The 'V' shape of the double tail fin should be moderate. It must have two anal fins, pectoral and abdominal.
Remember that when choosing one of these fish you should consult a specialist since their characteristics can be difficult to identify. Remember also that these fish are characterized by being slow, so it is essential that they live with other Goldfish or with species that have the same rhythm, otherwise they may have problems when feeding or moving, they could end up very stressed and poorly fed.
