thank you everybody! Cories orginate from waters with sandy bottoms, so they LOVE sand. Gravel can damage their barbels. They sift the sand through their gills and eat the morsels of food they find :)
I have never seen black cories! Could you post a pic?
i will thanks so much! I will get them in a couple of weeks!
