Currently have one senegal and one ropefish in my 75g looking to put more fish in. I am getting another senegal and one or two more ropefish, but I want to have a peaceful mid-high water(preferably schooling) fish to add some colour to the tank. I was thinking something along the line of larger rainbowfish or discus, but I'm up to all opinions. I don't want anything that will chew up plants. I had some gouramis which destroyed my Aponogeton and i would not like to relive that.
