It's been quite a while (or at least it feels like it) since I've had anything like this happen. When I got back from spring break a few weeks ago, I braced myself for the worst, but hoped that everyone would be fine when I got back. Luckily I didn't have any deaths the day I got back, and all of my babies (including every
betta 
) were alive and well, so I did water changes and fed everyone and everything seemed to be fine. But just a couple days ago I lost all 3 of my guppies, my balloon mollie, and two of my corycats overnight

The only survivor was the first corycat I ever had named Hermes, who is my little trooper and has survived through quite a few mistakes of mine. One of the guppies appeared to have some kind of mouth rot, but other than that everyone looked okay (aside from the fact that they were dead). No injuries, no
ICH, no fin rot, nothing. All water parameters are still in check. Now it's pretty hard for me to look at my 10 gallon with just Hermes in there by himself
