Aquarium Update

So today, unlike usual, our fish Cow was staying near the bottom, not the middle like he usually does. Also, Fish started to venture down further into the tank, closer to the other fish. Extacy was out in the open today instead of being behind Squidward's house like usual. Meep, however, has not changed his behavior at all. He still floats in his corner against the glass being anti-social. All of the fish have feces attached to them at this point . Thinking that if we scared them it would fall of, we tapped on the glass and it actually worked. There's also a buildup of feces at the bottom of our aquarium which is why, when we did our water quality test, our nitrate level increased from a 5.0 to a 10.0. To help with this, we added plants which help to lower nitrate levels. Our ammonia level went down from a 1.0 to a .25 which is really good, keeping our fish healthy. The temperature of our aquarium has stayed the same since we began.
