Ive had my 180 gal for around 6 years and want to change it up. Some of my very old fish have passed away recently and I'm ready for a change. Ive taken out all decorations. It currently is sand bottom with a Motoro Ray and Peacock Bass (might give away). I want the tank to look nice but I know i can't do too much with the ray. I can't decide between one or two more large fish like an Arowana or some large community fish (Would give away bass). Considering all ideas.
