We were thinking of getting a small school of corydora for our 55gallon. Without realizing we could have gravel or sand, we just assumed aquariums have aquarium gravel and bought a bunch of it. It's the small smooth colored kind.
Question is - are we fine to have 6 or 7 corydora with the small aquarium gravel or will that hurt them? Thanks!
