Temperature (F Degrees): 48.0
Nitrite (NO2) ppm (mg/L): 1.00
Water Change: 1gallon - 1gallon
Number of Fish Removed: 1 (due to rocks)
Lost one fish today, I'm fairly certain he was not a weak one, too. He was hanging out near the rocks and was pinched. I don't understand how it keeps happening because the rocks are aren't able to wobble or anything. The one weak fish is still weak, too. Today I cleaned the bottom of the tank and filter, changed one gallon of water, and tested nitrite, which has not changed. I moved the bubbler to the side of the tank today so that it is not blocking off access for the fish to use both sides of the tank, they seem to be afraid of it, and they tend to stay on the right side of the bubbler because of it. Fish were fed at 7:30 am, 10:00am, and 3:00pm.
