Hello everyone! I know I ask a lot of questions on here, I just want the best for my fish. Anyways I have a 32 gallon tank that I'm currently cycling and I wanted to transfer my substrate from an established 10 gallon to the 32 gallon to speed up the process. I have 2 Cory's in the 10 gallon which I will be housing in the bigger tank once it's cycled. Can my 2 Cory's live without substrate for a few weeks until the bigger tank is up and running? Also I know that Cory's need to be in larger groups these 2 I rescued from a pet store that doesn't take good care of their fish.
