I recently bought some new gravel. However, once I added it to my tank I realized that my new substrate is WAY too big for my Pygmy Corys to sift through.
I do not want to remove the gravel so would it be better if I created a small sandpit as a place for them to scavenge for food? Or would they be fine eating off the large gravel?
