First, the volume of map fish is relatively large, and it needs a large fish tank to raise map fish.
Secondly, map fish are carnivores, and they eat a lot, so it is not a small expense to feed a lot of live bait every day.
Third, map fish not only eat a lot, but also have a lot of excrement, so it is difficult to keep the water clean.
Brief introduction of map fish:
Turtlefish (scientific name: Astronotus ocellatus) is a species of cichlids and Turtlefish. The body length is 33 cm, and the maximum weight is about 1. 1 kg. The fish body is oval, with flat side, big head, big mouth and wide fins. Not only has teeth in its jaw, but also has a group of pharyngeal teeth.
The teeth in the jaw are small and can be grasped, while the teeth in the throat (pharyngeal teeth) are used to manipulate and handle prey. The base of dorsal fin is very long, from the back of the corresponding part of the poisonous fin in the chest to the caudal stalk. The ventral fin is in the chest position, and the tip of the fin is pointed. The gluteal fin is symmetrical to the dorsal fin, and the male end of the fin is long and sharp, the female is slightly round, and the caudal fin is fan-shaped.
The body color is black or dark brown, with irregular orange-red patches scattered around the body and red stripes in between, which is named after the map. There is a round black spot above the base of the caudal fin, and there is an orange-red ring around it, which shines when swimming, like a summer star, hence the name "caudal star fish".
Mature fish, the big black spots on the tail stalk are shaped like eyes, which can be used as protective colors and attractive colors, making other fish confused and easy to become Chinese food for Tuli fish. Before the fish reaches sexual maturity, the male and female characteristics are not obvious, and it is difficult to distinguish between the sexes.
