I have a group of 6 corydoras metae in a planted 33 gal and I'm considering redoing the tank. It's been running for over 3 1/2 years now and needs a change. I currently have a sand over soil/peat substrate and I'm considering a change to Flourite or Eco-complete. Is this a good option for my corys? I know they prefer sand.
