Sand Vs Gravel? Yes, this conversation again. Lol

I screwed up by not knowing better. I put in small gravel and later got cories. They seem to do OK on the gravel; they are fat and happy.

Your Cory's will do just fine on the gravel, don't panic

You can change your substrate if you want. I did that going from gravel to sand. I think it's better to not do it all at once though. I only did a quarter at a time to give the beneficial bacteria on the substrate a chance to replenish itself.
