As the owner of three potential giants (CK, pbass, black ear pangasius) and a medium-sized pleco, I've been told my 60g is overstocked. As of now, everyone in my tank is doing well; none of my fish are over 7 inches. I wish I could keep them all, but my tank limits my options. I am looking at an arowana, a Lima shovelnose, a Bichir of some sort, or something new that shows up along the way to add to my tank. However, I know that this will require a stock adjustment. I do not want to get rid of my CK or pbass; they're my two favorites. My black ear pangasius is awesome, but he's really boisterous and gets in the way of my resting CK, and will repeatedly bump into my fish, which I'm guessing irritates them. My pleco doesn't do very much, but I read that they produce a lot of waste and aren't good for the filtration. Those are the two fish I'm willing to part with. What do you guys suggest I do? An upgrade is eventually coming for my tank; I'm not completely sure of the size, but I will let you know when the time comes.
