The first point is the shape of the mouth. The parrot fish's mouth is a standard straight mouth, while the mouth of the ingot fish is T-shaped, which is often called crescent mouth, and cannot be closed. However, these two kinds of fish can't be well distinguished in mouth shape.
The second point is the head. The head of Acer truncatum shows a smooth arc, but the head of parrot fish is protruding, especially the protrusion of adult parrot fish is more obvious, which is also a big difference between the two.
The third point is body shape. The standard octopus has a short and round body, while the parrot fish has a long and flat body.
The last point is the difference in size. Octopus is mostly between 15-20 cm in length, while parrot fish is more than 25 cm in length and weighs more than 1 kg, which will grow faster than octopus.
On the other hand, parrot fish is a variety of blood parrot. The protruding part of its head is sarcoma, and its body color is mostly red, and its life span is about 8 years. Moreover, parrot fish is more fierce and funny than other common subspecies, and it is suitable for keeping in tanks. The price of this kind of fish is relatively cheap, and the fry is about 15 yuan.
Acer truncatum is an improved variety of the third generation, which is smaller, bigger, with convex eyes and an inverted A-shaped mouth, similar to a peach heart. Because its body shape is more like Yuanbao, it is called Yuanbao fish, and the current market price is between 40- 100 yuan.
