I have had a 75 gallon tank for about a year now. I have a green sunfish, yellow bullhead catfish, a koi that will be moved to a pond when it grows, another uknown sunfish (I think it might be a green hybrid). I also have what I was told was a pumpkinseed sunfish when my brother gave it to me, but it seems to have stopped growing, while the green sunfish has passed it up, which leads me to believe it may be a dollar sunfish? I recently added another 75 gallon tank and connected them with 4" PVC, it's all unfinished for now, but thought I would post some pictures if I can figure it out.
