I have a 300 gallon commuter tank with a 20"+ Jardini, few gars, TSNxRTC and few birchirs. My freind is giving his Silver Aro around 20" away because he is changing his setup. His silver is about 20" but the silver is much skinner then my jar. I was planning to put him in but never try having other aro with my jar. Do you think this will work?
