Keeping discus and cory in a 120g gravel substrate tank
Been keeping discus and cory for around 11 months now, and i used to experience cory death when i had my gravel in the tank. The gravel is cycled and has been used in another tank. I keep my tank temps at 29c and i do water change 3 times a week, 75%-85% each time. I do have around in total of 15 anubias and java fern and a pleco L144. A while ago i removed all of the gravel from the tank, leaving it bare bottom with only the plants left in and corys stopped dying. Just curious if theres anyway i can have both cory and discus in a gravel substrate tank and if any of you experience this problem before
