My fish have been dying for thecpast several days and I've noticed a strange pattern. They are danios, to note. I lost 5 last night and found them this morning floating and bloated. One died just a moment ago when my back was turned. It was bloated, floating with its fins out stiff. There was blood pooled in the area around its gills and in the area of its pectoral fins.
The nitrate is fluctuating between 0 and 10 ppm with water changes. I've been dosing with aquarium salt throughtout the day. I recently discovered that they're lights have not been turning off at night, and they seem worse off when I can't get into the classroom to turn them off at night. The ammonia and ph are ok.
I've been vacuuming the gravel and feeding twice a day, only as much as the can eat in a few minutes.
Is there anything anyone might, please, suggest I do to save them. I can get to a pet store tomorrow, so I can pick things up too.
