I have spent all day trying to find out how long it takes for a cory to grow from fry to mature size? If you know I would appreciate a general answer, thanks.

Hi Joanne,

That is not a question for which anyone can give you a definitive answer. In my experience, most of my fish reach sexual maturity in 9 months to a year - or a wee bit longer. Certainly, most fish have reached full adult coloration within that time frame, however, that does not mean that they are not continuing to grow at an imperceptible rate for many months beyond that.

This is one of those questions that cannot be answered with any real authority, as there are many variables that affect the rate of growth and sexual maturity, including food, temperature, housing and the individual specie, itself. All we can do is relate our personal experience, which may vary widely with each individual fish keeper.

In simple terms, as a rule of thumb, I consider my fish "mature" at 1 year of age. Remember, your mileage may vary.

I'm sure this was not the answer you were looking for, but I hope it helps. - Frank

Hi Joanne

What do you mean by "mature size"?

breedable fish? Show size? obtaining adult colouration?

There are going to variables to each of these questions dependant upon species. Frank's post above is a very good general rule but there would never be a guarantee. I have seen a batch of small bronze corys (TB) split in two - one half going in to a 24" community tank & the other half going into a 48" high-filtration tank with no other fish - the 48" was fed specific high protein dry food & live foods. the community tank was fed a "pinch of flake". After a few months the growth difference was staggering. This is just to emphasise that feeding & water conditions can have an impact on growth rate & therefore timescales to maturity
