Lost one fish today to another rock incident, removed this rock from the aquarium in hopes to end this problem. There is only one rock left in the aquarium now, it's small and it has not caused any problems so far so it should be perfectly fine remaining in the tank. Changed one gallon of water today, cleaned the sides of the tank and removed food waste from the bottom of aquarium, fliters were cleaned, water quality was tested, and nothing has changed since yesterday. Fish were fed at 7:30am, 10:00am, 3:30pm, and 5:30pm.
