In adulthood, their length can reach about 20 cm.

However, the pineapple fish raised at home generally can't grow to this size, because they have higher requirements for the surrounding environment.

If they are not carefully raised, their development will not be very good, so their length is relatively short.

Therefore, attention should be paid to water quality, water temperature, feeding and various problems when breeding, so as to grow well.

1. How big can pineapple fish grow? Pineapple fish is a common ornamental fish. Because of its beautiful appearance and bright colors, it is very suitable for breeding and viewing at home.

It is also a relatively large tropical fish.

In adulthood, some people can reach more than 20 cm in length.

But for tropical fish raised at home, their length is difficult to reach 20 cm.

Because they have high requirements on the environment, various factors have great influence on their growth and development.

If we don't pay attention to control the surrounding environmental factors in the usual feeding, it will easily lead to their poor development, so their length is short.

Therefore, we need to pay attention to many problems when breeding.

For example, the water temperature is preferably between 26 and 30 degrees.

For example, feeding, try to feed every day, and you need to choose nutritious animal feed.

Second, how long can pineapple fish live? Pineapple fish's life span is still relatively long.

If it is a wild species, that is, pineapple fish living in natural waters, their life span can reach 10 years or more.

However, if pineapple fish are raised at home, their life span is generally short, and 7-8 years is relatively old.

Because they have high requirements for environmental factors, they need to strictly control the surrounding environment. Once the environment does not adapt, it is easy to affect their survival.

Especially the water temperature, try not to be lower than 26 degrees.

There is also water quality, and its disease resistance is relatively weak. Poor water quality can easily lead to bacteria multiplication in water, so pineapple fish will get sick and his life will be shortened.

There is also water quality, and it is best to use acidic water when breeding.
