The odd things to me were:
- Those white markings that appeared to not be a fungus or parasite. Internal infection could make sense.
- The morning it died, one eye was starting to bulge. I'm thinking bacterial/infection because the usual. "poor water quality" culprit was not the case, unless hypo counts.
- The lower fin, along it's bottom side, appeared puffy about from the body to about half way down. Could that be swelling from infection?
- The Tang and Engineer Goby died almost exactly the same time, so I'm guessing it's the same issue. The Puffers were a few days ago.
I know they had Ich, but all died after that had cleared up. It seems like two separate things, but possibly the Ich caused more damage than I thought? I'm kinda leaning away from that though, as they all looked good for at least a couple days after their spots had disappeared. They were acting normal, out swimming around, eating fine , no rapid breathing, etc.
