Sometimes I hate this hobby!

Sorry man. I hate it when stuff like that happens. Something must have found its way into your tank. Any piping above your tank? maybe some rusty water got into your tank. Maybe even some kind of spider or poisonous insect. You may never know what happened. What about windex? or some type of cleanser?

Well, I'm at the point that I agree that something got into the tank. I can't see any other possibility that makes sense. I just have no idea what got in or how.

Did another 30% change last night. Multi seems to be coming back! This is his third near-death experience - I've never seen such a tough fish! When I netted him, he'd been sitting, upside-down, on the substrate and hadn't moved in hours. No sign of life at all- Amazing!
