lol wow tuna. that guy must've had money t burn if he set up a tank just to put a can of tuna in it.the weirdest thing i have ever seen in a tank would be a ghost knife. i have seen weirder but they defy all that is normal for a fish lol. i have one i should know lol
I would have to say the first ime I ever saw a puffer. I was just casually looking into a SW tank and this guy just swam from nowhere and started staring directly at me. I had never seen anything so...interesting before.
