Question

I got a clown loach today and he is around 15cm is there a way you can tell how old he is?

Answer 1

Ask it when it was born.  Unless he has papers, you'll have to take him at his word.

Answer 2

There is no way to know for sure, as clown loaches are all wild caught.  As a rough estimate, clowns grow about 1-2"/year and their growth rate slows when they are about 6".  Keeping this in mind, I would estimate your clown loach is anywhere from 3-6 years old.  Clown loaches have a long life expectancy, so you should enjoy him for many years.   I have 6 of them (my largest is about the size of yours) and they are by far my favorite in my tank!!
