I had 9 neons the other day, now I'm only able to locate about 2 of them at any given time, they used to school really tight, and i can only find about 2 (give or take). I know they havent died, or at least I havent removed them from the tank, I've never seem em floating. Is it possible they died and my gouramis devoured them? I also know they didn't jump out of the tank, my tank is the only thing up against this wall, on white carpet, i'd kind notice a dead fish anywhere near it. Any suggestions as to where these fish may have run off to would be appreciated
