Wierd losses on JUST loaches and one Molly...

[TN Tanks]

When I left this morning, all my fisn in my 150 gal were fine, got home, I had 2 floating Clown Loaches, 2 sunk Clowns, and 1 floating Molly. Water parameters are great, no detectable amonia or nitrite, here is the rest of the stock:

10 or so angels
4 1 year old Silver Dollars
8, well now 7 mollies
3 surving loaches ( terribly weakly colored )
20-30 assorted tetras
2 common pleco's

Only thing i have been doing differently the past week was adding algea wafers for my growing plecos.

Should I be concerned about future loss, one of the loaches tail was eaten, and the molly was picked clean. Both floaters eyes were cloudy, didnt examine the others eyes. Tank looks good, has been around 82 degrees because I just added the mollies last week and I wanted to ward off ich. Any ideas?

Think maybe a brown out made it cold or a surge made the heater malfunction a while? (better than no theory)

or a sudden pH swing?

You won't ward off ich with 82, 82-84 makes ich spread and grow faster.


It has to be above 86 to even affect the ich

Dont think a brownout would have caused it, underground utilities, and my clocks were not messed up. I have 2 heaters in there just incase one malfunctions off, and I have a alarm on my temp so it beeps if it exceeds 84.
