Firefung Lohan retreat is the first retreat process that starts when it is in the transition stage from fry to sub-adult, around 10 centimeters. Some rohu may undergo multiple sand retreats. Desanding is a genetic mutation and is not directly related to time, some desand in a few centimeters and some for life.

Please note that repeated sand regression is not always a good sign, and this may negatively affect the appearance of the Fire Phoenix Lohan just like the consequences of repeated plastic surgery. Therefore, maintaining a stable breeding environment and avoiding repeated sand retreat is the key to raising Fire Phoenix Lohan.
