Loaches

[2day]

How old are loaches when they are about 5cm long? Cheers

It depends on the type of loach- what type of loaches do you have ?

 

[Lateral Line]

It also depends on the conditions they've been kept in, the feeding regime, and to a certain extent the individual fish. There is no realistic way to tell precisely.

It is a clown loach

Under 1 year. As Lateral said, there are too many factors, but 1" per year is about the ave rate of growth of clowns after they reach 2"-3" size, at the beginning the growth is faster, in fact the article on breeding clowns on loaches.com,
http/www.loaches.com/loachbreeding.html
says
At 6 weeks, they were 1" long total length, then growth slowed.
(but it is not obvious that the same rate would happen in the wild with less food available.)
