I've had a bare 40 gallon breeder with potted plants in it for about 3 years, with only two goldfish in it. Three weeks ago I decided to give away the goldfish and trade it for the community route. It was stocked with 1 bleeding heart tetra (only 1 was available, waiting on school), 4 black neons, 6 neons, and 6 cory cats <1". Everyone was doing great, water was stable.
Last night I washed and added 40 lbs of black gravel, did a 30% water change, and added two adfitional plants. No fertilizers were added. Detritus got a little stirred up but not too cloudy, and it settled pretty quickly.
This morning 3 neons were dead, 1 is swimming around weakly, and 2 are missing (likely dead, but I can't find them?). Black neons & bleeding heart look fine, cories seem lethargic. I did another 30% water change and checked the parameters, was shocked to see 0 ppm ammonia, 0 ppm nitrite, 0 ppm nitrate. Water is at 78 degrees. So what on earth is going on?
