I aquired a 4" Blue Jewel a few months ago, I seem to remember it swimming around fine. Now within the last few weeks all it does is hang around the bottom. It acts like it's in a daze or drunk like. Does not come up to feed anymore. I have to use sinking pellets to feed it. Water is fine Amonia 0 Nirite 0 Nirate 10. Water temp is 81. It's in the 110 gallon tank in my sig. Any ideas?
