HUUUUGE corydoras in my lfs???

Well, I wanted to add another cory to my tank (I now have 3) but in every fish/pet store I go lately I see HUGE corydoras.. and by huge I mean 3.5 inch long and extremely fat like they are on proteins or something. My corys I have for 2 years now are about 1.5inch long and they didn't grow since I bought them. They are 2 bronze and 1 albino. Will my corys grow to that size? Is this normal?

 

3.5 Sounds a bit large but my albinos were close. But they were very very spoiled food wise LOL

 

Haha.. I feed mine all kinds of food; from frozen artemia to zucchinI and they eat like piggies but they stayed small. I've had them for 2 years now and they are still around 1.5inch long. Is this normal? It's a 16g tank with a DG, a black molly and 3 rummynose tetras (survivors).

 

sure its normal each fish I'm sure has different genes and as long as they are healthy, that's what matters

 

Mine has the same I believe they are emerald cories

 

Green corydoras

 

My mama cory was a monster!
I bet she was all of 3.5 inches!

 

My LFS has a different type of cories (well, they claim they're a different type) and they are HUGE! Every bit of three inches, and they look disproportionately fatter than normal cories, too. I looked on the website but it must not be updated, as I didn't see them. When I go next weekend I'll take a picture

 

Theyare most likely some type of Brochis which are a cory relative. There re several kinds just like there are several kinds of Corys. As far as I know they need the same care and act the same way.
Here is an search I did
