Surely it cant be...?

Ok so once again my wife decided to be nice and buy me 3 corydorus...however these things are HUGE! Surely this is not a normal cory...

if the fish seems huge in the tank, the tank is too small

the substrate is also too rough for corydoras

Hello
It definitely is a Corydoras aeneus aka bronze Corydoras or green Corydoras.
How large is the tank ?

I also have some giant bronze corys females can be over 3inches in size , sand would be preferred for them in fairness

Thank you for your replies and I'm glad that it appears to in fact be a cory. Regarding the substrate, it's about a 3 foot long tank with plenty space for big girls like these, half of which is sand and half is crushed coral to increase my pH and Gh levels

Corys do prefer softer water so I wouldn’t bother buffering to raise the ph and gh unless it’s super low

At the reception last saturday at the new lfs, I saw some of those giants as well. But these cories ain't the only ones that can grow up excessively.

Had some peppered cories that large before, just sold as XL cories.

I dislike this dirty habit to produce giant fish or giant fruits, or giant vegetables

Some 7cm is considered a normal size for a female Bronze Cory, or 2 1⁄2 inches.
The substrate is good enough in texture and grain size. (You should see what the substrate is like where these fish naturally occur ). That said, if you could make them a beach, they'd appreciate it.
The very white colour, however, maybe stressful for some fish.

Although I confess that, long ago, when I first saw a large tank full of well cared for and full-size tetras, corydoras and angels, I was stunned by how big they can grow.

Should have been more precise : I dislike it when genetics is used to create gigantism that will be detrimental to fish.

This process actually happens in nature too but In smaller number so it’s not actually bad for the fish

Yep just like the human race produces 7 foot plus specimens sometimes, not harmful to them either.

At least we agree on that
