The growth rate of sandfish depends on environmen-tal conditions and the time of year. At medium size, sandfish grow on average 0.5 cm per month, corre-sponding to 14 g per month. Under good conditions they grow to a size of 300 g in one year. We still do not know how long sandfish live, but it may be around 10 years.
