Very confused by recent events in my tank. I added 15 Cardinal tetras to a fully cycled tank and in less than a week 11 have died.
There is 0 ammonia, 0 nitrite, and 5ppm nitrate. The tank is 55 gallons.
Admittedly, a couple got caught in the filter intake and died, but most didn't. To put things in perspective, and assure you it's not a water quality issue, I have 6 ottos in there that are completely fine. Can anyone guess what happened here? Could I have just received genetically inferior tetras? Unsure whether to add more or to go with another fish.
