I have definitely considered that Balton. Like all fish in any species, some co-exist, some don't. If you are willing to shift stock at times and keep trying, eventually you have to find a mellower fish (hopefully). I think I need to add a couple of larger top swimmers or maybe a cat or two though to act as a bit of a distraction. Normal dithers would probably just become a midnight snack for the jag now. I have held off spending money on fish for a while as I was saving for all the new camera gear. That being here now I can look at spending some more $$ on fish.
I couldn't agree more and your new camera gear kicks butt.
