Yesterday afternoon, I saw a dead Cardinal tetra in my 10 gallon tank. Another looked sick. I had 7 cardinals, and this morning all but one are dead (and I can't find one, but I'm thinking it's dead in the tank somewhere). The last fish that's alive doesn't look like it has long left. The fish have been perfectly fine for 4 months, the tanks parameters are perfect, and the shrimp and snails are all ok. The only thing I changed the day before yesterday was I got a new heater. I took the temp up a couple degrees (to 78f). And that was a gradual change. Anybody have ideas to what could've caused this? And what I need to do to the tank before getting more fish?
