Genes and feeding environment will affect the development of the red-nosed scissors fish, so how big it can eventually grow is not fixed. If it is a relatively robust fish, it grows in a suitable environment, up to 6 centimeters long. When raised at home, few fish can grow to 6 centimeters because of space constraints. Moreover, the cultivation of this kind of fish is more difficult, so it is not recommended to start with small fry. It is better to choose fish with a body length of about 3 centimeters to start feeding. Fish can grow to 4 to 5 centimeters if they get enough nutrition during their growth and remain healthy all the time.
The red-nosed scissors fish growing in the wild have a longer life span. Under normal circumstances, they can live for 4 to 5 years. However, today's red-nosed scissors fish are basically raised in captivity. And when they breed, they often take the way of inbreeding, which will lead to defects in their offspring. Therefore, the life span of fish will also be shortened. Even if they are provided with suitable growth environment, their life span will not be as long as that of natural fish. Generally speaking, their life span is only 2 to 3 years. If they are not well farmed, their life span will be shortened. Some fish even live less than two years.
