Does anyone know of any corys that like their water on the cool side permanently? I am wanting to put a couple in my goldfish tank, which sits at about 20C. I know that cool water changes will stimulate some spawning behaviour, but what about cool water all the time?

(formerly called Corydoras barbatus) would be fine at that temperature. It's not hard to obtain, keeping in mind that most shops are still selling it under its old name.

There are probably others, but I'm not much of an expert on corys.

I'm afraid no Corydoras will like 20 C permanently.

The only region in the world with constant temps all year round are the tropics, with approximately 30 degrees C (avarage of day and night) at sea level. All other regions have fluctuating temperatures

However, if one goes up a mountain, the temp will drop as well, on average 6 C for 1000 meters (thus approximately 10 C a mile)

SHOULD a Corydoras life in the Andes at 1 mile above sea level, this will be your fish. As far as I know, no such Corydoras can be found

However, regarding Corydoras accepting 18-20 C in summer, and 10 C in winter, next S barbatus, C paleatus and C longipinnis might be good alternatives

hi

S.barbatus is a nice fit to goldfish, already seen and works fine in unheated tanks in central Europe.

others cold-side-guys :
Scleromystax-species
Aspidoras-Arten (without pauciradiatus) !!
Corys:
C.paleatus
C.spec "greenstripe"
C.armatus !
C.diphyes !
C.ehrhardi
C.hastatus
C.napoensis
C.natterei
C.steindachnerei !
C. semiaquilus "Black Peru"
C. undulatus !

check out in detail...and check, what you can get .

Thank you all so much for your help. I've had barbatus before and wondered why I had problems, temp too high. I have written down all the names and am on the hunt. There are a few here that I know I can get.Thank you again
