Okay, for week or so with our pl*co was fine, no question about it. Now though, its just an eating machine. Which is where my question comes from. As s/he moves about, there is a long string coming from the underside. My assumption is excriment (poop). So, do they have a constant chain of vial nastiness to clutter up a tank? Or is it perhaps some sort of infection? If needed, I'll find a way to get a pic up. It breaks off the fish easily, so I know its not a work or parasite.
