I just can't keep corys!

They're getting plenty of sinking pellets and wafers. No issue accessing the surface. No salt. Tank is maybe a little warm - like 80F. But still I haven't had luck keeping them at 76F either.
 
I have to be honest and say that I have not had the best luck with cory longevity either. I have tried multiple times with the same results as you. I have one lone brochis I have had for several years, and one lone sterbai (from a school of 7) that are surviving and doing well.
 
I think it's important to note that not only are many of us having trouble keeping corys, but those of us making these reports are all very knowledgeable and experienced aquarists.

Seems to me that the common practice of labeling corydoras as a hardy fish needs to be halted. It's just plain incorrect. Almost every entry in a fish database describes them as easily kept and yet here we are having all of this trouble. Not that I expect all of the books to be rewritten but one has to wonder how on earth a fish that can't seem to survive in some of the most well kept tanks has earned a reputation for hardiness. It just makes no sense.
 
WOW. I have kept coys for years. Once had some that was almost 7 years old, but died during my second move (forgot to plug in heater--temp dropped into mid 60s :( )

My 120 once had almost 80+ corys of many different kinds (some very rare!!)--it is now a reef.

IMO--Corys are amoung the hardies of fish. Cannot think of what is wrong.

:iagree: As one says, experience varies so just because one says his cories are really easy to keep doesn't make it an ultimate statement that will apply to everyone else. Duh!
 
I do have 4 Corydoras Aeneus that I've had for some time. Two actually helped cycle my 1st tank..... before I knew any better.
