I will post a pic of the plants that are in my Peacock Cichlid tank if you like. I have a few yellow labs in there but they behave pretty much the same as the Peacocks.
Also have a 46 gallon planted with Angelfish and a 150 gallon planted with Discus and Angels. Both substrates are 90% covered by some form of plant.
