I've had 2 fish croak on me over the past week and I can't figure out if its just a bad coincidence or symptoms of a greater problem.
I lost a red spot rasbora about a week ago, and when I got home last night (away saturday & sunday) for Easter, one of my black neon tetras (what was left of him) was stuck to the filter intake.
Ammonia = 0
Nitrite = 0
Nitrate <12.5
I also did a 20% waterchange friday night.
None of my fish have shown any signs of illness. They all eat readily and have been behaving normally. The black neons often hang out in the current of the filter return, but like I said, all have been exhibiting normal behaviour. No signs of fungus or parasites either.
My tank has been high, 84 degrees for several months. (I got a cardinal and a platy a while back off craigslist and thought I might have introduced ick in the tank so I salted and turned the heat up - the ich never materialized, but I never turned the heat down.)
Yesterday I turned the heat down to 80.
So, any ideas on what maybe killed my fish or should I just think of it as a bad coincidence and move forward with the aquisition of a pair of cockatoo apistos?
