Long story short, I upgraded from a 29 gallon to a 75 gallon. I had a Green Terror and a FeatherFin catfish that I had for over 1 year before upgrading the tank (reason for the upgrade) with absolutely zero issues. Once I upgraded, everything was great. I did throw a lot of variables into this right away though and am trying to figure out what happened.
I added 5 Giant Danios, 3 Firemouths, and a Blue Acara. I also had Dempsey for a few days but he was too much larger than everyone and causing problems so took him back. On top of this, I tried a Fluval FX4 instead of dual AC 110's and then decided I did not like that as much and switched back to the 110's.
So there were new fish introduced, a couple filter changes (always using my old media, never lost cycle) a couple large 50-60% water changes, etc. So I very well could have not been paying attention the night before we left when I switched the filters back and only used half the amount of Prime that I should have.
I left on Wednesday and a buddy stopped by Friday and said all fish looked great. Came home Sunday and the catfish, the GT, the Acara, and 1 FM all dead. This morning, the other Firemouth was about 90% dead and one of the Danios were dead. I immediately checked water parameters and got 0, 0, and 5-10 nitrates max.....so water was perfect.
No visible signs really on the fish, except maybe a couple that were struggling looked like their slime coat was a little funny? Hard to say.
What's odd, is the fish that are left now: 4 Giant Danios and 1 Firemouth are all completely healthy, active, eating, etc. etc.
I did a large 90% water change this AM and wiped the inside of the tank down and vacuumed the bottom (which was already clean).
I ordered this Ick medicine just to be safe, but I really not know if that was it. I wonder if I messed up my Prime like I said above and it got some of them? Or maybe if my buddy over-fed them?
I did notice that some of the fish that were affected were vey twitchy and spastic while still alive this AM.
Sucks to lose those 2 fish after growing them for a year and of course the new ones as well. I'm just at a loss as to what happened.
