I have these small corry catfish but today at the pet shop I saw these HUGE ones! I didn't know they could grow that big. How do they do that? I have one corry catfish that is 8 years old and he is nowhere near as big as the ones I was at the pet shop.

It's about their age, their species and the size of the tank they have been kept in. Babies will be smaller than adults. Most corys grow to 2 1/2" -3" but then there is the Corydoras Pygmaeus, or Pygmy Cory, that only grows to 1" and the Corydoras Barbatus, or Giant Cory that can grow to 5". And then, if they are kept in a small tank, they are not allowed to properly grow and their growth is stunted and they become deformed. Chances are that you have the typically standard size of 2 1/2" to 3" and they will never get bigger than that. If you want a large one, you have to know the name of the species you want, and then specifically search for that species.

The female corries are almost twice the size of the males. I have many different kinds and this seems to be the norm. Emerald Green corries get about 3", which seems to be the biggest, down to the miniature ones about 1"

There are many different types of corydoras catfish and there is at least one book devoted entirely to corys------some do get rather large----also-------the size of the container does factor into play----in general fish don't tend to outgrow their tanks----this is especially true of the corys.

What you saw in the petshop was a "hoplo" catfish. Looks just like corys. Greenish right? Look in your browser under Hoplo catfish and you should find pics.

There are different species of Corydoras. Some are considered "dwarf" species (2 - 2 1/2"), others are definitely NOT (almost 5")!

& another one is exactly right, but add to that mix there are hundreds of species of cory cats and some are practically impossible to tell apart except for size.

it depends on the size of the tank and how many other fish are in the tank they grow to fit

there are many many different types of corys and also dwarf corys...and many of them look very similar to each other when they are young.
