Do I need more bottom feeders in my tank
I currently have a 55 gallon planted tank. It has 12 rummy nose tetras, 12 cardinal tetras, 5 rams, 2 dwarf plecos, and 2 clown loaches. Do I have enough bottom feeders in the tank currently? Should I add cory's to the tank? If so how many? Also I plan on adding some discus to the tank. What would be a good number to add without over populating my tank? I appreciate the help!!!
