Breeding Clown Loaches, Is It Possible?
To breed clown loaches, they need to be around 2-5 years old and should size up to about 6 to 7 inches. Breeding this species in a community or in captive, in general, is a daunting task predominantly due to how hard it is to find a breeding pair.
Your chances increase significantly if you have around 4-5 males for every female. These males will tirelessly chase the female until she lays the eggs. The gestation period is approximately 14 days, and babies will be able to swim by that time. Females are more stocky than males, and their tales are shaped more pointy.
