Where I am from , temperatures are a consistent 27-32 degrees, and while this temperature is perfect for keeping fish from the larger rivers of South America, which have warmer temperatures all year round, it is certainly challenging to specialist fishkeepers like us who have the darned luck to take a preference to fish that originate from mountain streams and smaller tributaries of the main rivers, which tend to be much colder.
Hence I now keep a list, which I am sharing with readers of this blog (if you still exist, since I don't get comments) as well as a record for myself which is accessible from any part of the world. This list consists of all known species of corydoras which are likelier to survive in our climates.
