So since we've become more aware, in the last week I've been specifically looking to see all 7 of our Dwarf Cories at once. They were a mistake for this 90g - cute, but so small they generally escape my attention. I've noticed in the last week that even when the cories are stressed (during WC), and both the dwarfs and punctatus are all hanging out together, there are only 6 dwarfs. I see 6 dwarfs quite often - but just 6.
We suspect that perhaps this all started with a dwarf cory dying and us not noticing. It's hard to be sure because the tank is so large, the dwarfs are so small, and there are a million places they could hide. But I would bet a lot that there are only 6 dwarfs in there. The other a victim of disappearing fish syndrome (we took out the driftwood a few days back to do a really in-depth vacuum, so we would have found a body then).
Also, regarding the hydrogen peroxide, I realized about 30 min afterward that I did SO MUCH spot treating that I totally OD'ed the tank. Cue another big water change. Also it was such an OD that I probably killed my bio filter. AARGH
